1952 GM PD-4103 ex-Greyhound - Frozen in time

I just purchased (summer 2012) a General Motors Coach PD-4103 yesterday off a farm in North East PA. It was sitting in the same spot since the 1960s when it was taken out of service with Greyhound. It is all original and hasn't been touched since parked. It was like time froze around it.

It is a 1952 PD-4103, Serial #725. All glass is good besides a few side windows. Both aluminum bumpers are straight too. Arrow turn signal lenses are good and even the reading lamps inside work when I took a battery to it. Heater fans kicked on too! Didn't try to fire it up yet, but the engine does turn over freely.

Would love to hear from anyone who is familiar with this vintage bus as far as restoration and mechanical matters...

Thank you for the interest,
Kevin Lewis

I really hope to get some more information on this bus. It would be greatly appreaciated. I do not know much about buses. Just found this bus on a farm and bought it on a spur of the moment type deal. | Sep 19, 2012 | 8:13 pm

Kevin, thanks again for submitting the above photos to Looks like you'll have your hands full restoring her, but should prove worthy.

You inspired me to dig up some photos I took back in 1997 of a beautifully restored GM PD-4103 similar to yours. I just posted them here on the site:
Hopefully it can serve as a template for you. All the best.

We have a 1951 PD4103 #057 that we are currently converting to a motorhome. What are your plans with yours?

Kevi Lewis | Oct 11, 2012 | 5:18 pm

I really dont have any plans yet. Because it is all original with all seats intact I would probably like to see it stay original. It even still has the original greyhound van lines medical kit in it!

Mary Heiser | Oct 11, 2012 | 6:43 pm

We would love to see some pictures of the inside with the seats and luggage rack if you have them. If things change we are in need of parts and would be interested in buying it or just parts. We especially need the front windshields - ours are cracked. I inherited the bus from my brother who passed away in Feb. 2012 (he was a Vietnam Vet and is was buried in Arlington)- he had owned it for 16 years and worked on it a little at a time until he got sick. His dream was to travel and live in it. We couldn't bare to scrap it and since we do a lot of RVing ourselves and own a 88 Motorhome we plan to use parts for the Bus, we decided to continue with his dream and finish it. It had actually been sitting and had not been started for about 3 years (in North Carolina). My husband and a friend drove up to North Carolina in April and was able to drive it back to Florida (where we live) with no issues. We did put brand new tires on it though before they left North Carolina. There are not many of these buses around - there was only 1501 made and our number is 57. My email address is if you want to send the pictures and I can send some of mine to you too.

Kevi Lewis | Oct 12, 2012 | 10:23 pm

yes i heard the windshields for this model are very hard to find. Luckily both of mine are intact. I sent you over an email earlier this afternoon with pictures of the interior which is in very good shape. I haven't really considered selling it but again i dont really have plans for it either so I would like to see it go to a good home.

Al Bianco | May 08, 2013 | 2:23 pm

Hello Kevin and Mary;
Guess what? I own S/n #1461,which was converted in 1980 by a Calif. Trucker,who did a real good job,to make it function for day and night use. Seats up to 14 and sleeps 5,due to convertible beds in front and rear bedroom. Remains in it's tradition as the most reliable model GM built,it would be the one to go to when all others would not start or run. Has original 6-71 with 90mm Injectors and By-Pass oil filter ,and used to run at over 90 MPH in calif,L.A. to Vegas,before City of Fresno put in Charter fleet. Now runs with much power ,since I installed smaller Metric tires (255 ,and 235 front),which I recommend,as rear end gears are too tall.(High-355:1)
All Amsoil lubes allows very LONG service intervals,and EASY winter starts. Have same drivers windshield problem,(neighbor?? put rock thru it after $700 replacement 2 weeks prior.)
I will try to send pics,but the ONLY issue it has is Esthetics__New Paint,and some rear glass,which I knocked out one day.
Wish you the best,as you will stop traffic on the road all the time. Everyone,young and old,will stare at it.And that is a problem with these coaches-They take over your emotions,and become a part of you. Possibly why you bought # 725,which by the way has the same pass. side mirror as mine,some did not,like # 72 ,like Mary's
Suggest you get with an Amsoil dealer or me on pre-start lubing for your engine Kevin,or maybe you have already done that. Those engines love a 15W40 lube in Synthetic,as old 40 wt.petroleum takes more energy to start and maintain oil pressure,get it in Gear boxes for sure, since sat so long.Do not worry about leaks,as bad seals leak regardless of lube,but best lube never fails to protect.
Attempting to assist in areas,you might not have info on,so pardon any sense of pitching product.I really wish to help,in areas,some maintenance people may not have latest tech knowledge,and that is what I do all the time, Vehicle Maintenance Technologies.Including Hydrogen on Demand fueling ,with your diesel to clean exhaust and reduce fuel consumption dramatically.Soon on my rig.Best regards, Big Al B.559.281.4804

Mary Heiser | May 08, 2013 | 2:57 pm

Al,thanks for your comments. You right we do get the looks!! We nearing the end of our conversion - hopefully have the interior done enough so we can start camping in it. Sorry to hear you got a rock through your windhields but curious to know where you had them made? My direct email is

Kevi Lewis | May 09, 2013 | 5:52 pm

Al, my email is

Al Bianco | May 10, 2013 | 12:03 am

Thanks Kevin; Small world indeed. Is That you on Right or on left in Pic.I think it is guy on right,that I talked to.
Will send quick note soon. Thanks, Big Al B

Kevin Lewis | May 11, 2013 | 9:58 pm

in the bottom picture I am the one on the far left

Lou Lupo | Jun 01, 2013 | 6:55 pm

I also have a 1952 GM 4103 #1184. I drove a few times and on the way to Biloxi it broke down (overheated a bit) but I got it back to Philly. haven't done much with it lately but I would like to.

Mary Heiser | Jun 01, 2013 | 8:50 pm

Hi Lou,

Do you have the original windshields or have you replaced them?

Lou Lupo | Jun 02, 2013 | 2:23 am

I have the original windshields (I hope?) I have not even seen bus in a few years. I keep it stored in NJ and it was a good location since it was a bus repair facility (US Coach) but they have moved so now its just a school bus yard. I'd better go check it out and move to closer to home. I will take some pics ASAP.

Mary Heiser | Jun 02, 2013 | 5:56 am

We know US Coach - we have ordered parts from them. Our windshields are cracked and we will need to eventually replace them - either from another PD4103 or eventually find someone to make them. It's been difficult because for someone to make a mould, it would be costly. If there was a handful of other people who needed windshields it would cut down on the cost and the mould charge could be split among all of us.

Al Bianco | Apr 21, 2014 | 7:58 pm

Hello All;
Well I am feeling a little sad,as I have decided to find new home for the Coach described above. Will take offers which are reasonable for this real "Art Deco" classic,which should not be lower than $12,000. Will describe all factors about the coach,including what I believe will be needed to put it directly on the Road. Really only esthetics ,such as paint and some glass. Driver Windshield was vandalized in 2001,and hasn't stopped me from enjoying the drive,all the time.I compute it will take about $3000-4000. to make it road ready,plus Paint on non-stainless sides and Rear/front.
Will gladley talk to interested parties at 55.281.4804 or al@ Thank you for any interest,and Regards at EasterTime.

Mary Heiser | Apr 22, 2014 | 6:04 am

Al, you may want to advertise on We are still searching for windshields...we do drive it locally but it hinders us from going out of state or long distance. We may have to settle for lexan. The cost to have new windshields (molds) would be over $5,000 - so we are still in hopes of finding another bus with good windshields. Good luck with selling it!

Kevin Lewis | Apr 22, 2014 | 7:10 am

Good luck with selling your bus! This summer is going to be the last one for mine too. Just sold 3 Vehicles last week including 1 bus. Everything has to go!

Al Bianco | Apr 22, 2014 | 11:50 am

Thanks folks. You went to much effort,Kevin ,to get that coach alive again,and you are continuing to do so. I will take your advice Mary,but I am sure that anyone on this blog,knows and appreciates what these historical drivers really are,and would be much easier to explain their benefits,and who, would love to pass along info about what is going on with them.
All the best and Happy Easter to All. Al B

Lou Lupo | Apr 27, 2014 | 7:31 pm

Sorry to hear that you are selling your bus and I am wondering IF I should do the same. I would hate to but having already "broke down " in an antique is not a good experience. I will attempt to get it started this Summer and take a trip. Thanks for the info Big Al @Al Bianco

Denis | Apr 28, 2014 | 4:55 pm

I have a 4013 and I could not believe that there is one out there that is one number from mine. Mine is 4103-726. My windshield is lexan and is 10 yr. old, it needs to be replaced.


Kevin | Apr 28, 2014 | 5:26 pm

Just got mine up for sale. I have to do something with it before next winter even if that means scrapping it or parting it out. Hopefully will find someone to buy it!

Mary Heiser | Apr 29, 2014 | 5:10 am

Denis, where did you get your lexan windshields made? We are considering email is

Denis | Apr 29, 2014 | 8:31 am

I took the old glass out and laid it on a big peace of cardboard. from there I make a pattern of one big windshield

ken brown | Jun 03, 2014 | 7:19 am

My Wife and I recently bought a 1952 PD 4103-716, living in it and remodeling the uld convesion, a lot of wiring and exterior paint work. What a blast.

Mary Heiser | Jun 03, 2014 | 10:14 am

Ken - In what state to you find it?

ken brown | Jun 03, 2014 | 11:10 am

Way out in the desert in Laveen, AZ

Charles Seaton | Jun 23, 2014 | 11:59 am

I am catching up on this late, but I love your '03. I have not seen too many of these without silversiding but yours would look great just painted. She looks straight and this should be an interesting project. Good luck!!

Smoggy | Dec 16, 2014 | 3:58 pm

Just wondering if you still have your bus for sale ? Kevin

Kevin | Dec 16, 2014 | 5:18 pm

Yes I do

Tommi | Dec 19, 2014 | 3:04 pm

Kevin, hi, how much for your 4103?

Arthur j brinkerhoff | Feb 05, 2015 | 11:31 am

Sure enjoy the input on the site, I am looking for a 4104 classic enough for me and the wife. Plan to travel and we love the GC! I know most of us bus nuts, lack,the serious money it takes, and we compromise to enjoy the life style we choose. I know there are glass manufacturers out there, if we all got together and pooled our resources, we could get the glass we need. They do it for classic cars, maybe they would do it for us.

Mary Heiser | Feb 05, 2015 | 7:22 pm

Coach Glass still makes the windshields for 4104's and 4106's unfortunately 4103's are not as easy to find unless you find another bus.

Arthur j brinkerhoff | Feb 06, 2015 | 12:27 pm

Hi Mary: gosh if coach glass has it for my dream bus, maybe there isn't that many units remaining for the 03. I know cost is another factor for us. I once owned a 49 Mercury coupe, the rear glass was a 3 piece unit, I,found a company in the Philippines that made the unit, and claimed they had the resources to manufacture any piece, I don't know if that included buses or not. And on top of that, it was twenty years ago. So who knows

Al | Feb 06, 2015 | 12:54 pm

Tommy;Have silverside 4103 #1462 and with sad heart, am willing to part with to one who appreciates what history that model brings to all of Coach reputation It has a strong drive drain with extra H P and dry air cleaner ,and Vortex boost,runs at 2500 RPM ,with resided tires for lower gears on 3.55:1gears.great older conversion with hardwoods,seats 15 on rearsettee/bed,sleeps 5 ,2 captains chairs opposite a couch behind drivers position . Needs tlc,paint and some glass AND drivers w/shield repair. Have pics as needed. Asking US 12,500.00 Firm. Call 559.281.4804. Fresno,Ca

Tommi | Feb 19, 2015 | 6:53 pm

Al, sorry, just buying a PD 4103 now

Mary Heiser | Feb 19, 2015 | 7:43 pm

Tommy where did you find your PD 4103?

Tommi | Feb 20, 2015 | 8:33 am

Mary, 10 minutes from my place. Calgary, Canada.
Was looking all over the US and found it next door. LOL

Tommi | Feb 20, 2015 | 8:38 am

does anyone know how many 4103s are still running out there?
Does anyone have a parts bus?

Mary Heiser | Feb 20, 2015 | 11:54 am

It's difficult because they on produced 1501 buses. Luke at US Coach in New Jersey works on the older buses and has parts. He us known in the bus community.

Al Bianco | Feb 20, 2015 | 12:46 pm

Tommi: Happy to see that happen. Is it converted? Check rear diff for ratio and if 355:1 you can size smaller tires capable to handle prox 23K pounds gross weight. that will be great on hills I'm using 255X22.5 but 275 will help. Also Change to Dry Air cleaner easily at used truck air cleaner parts. Can help with that too. Lots of luck,fellow 03" lover.

Arthur j brinkerhoff | Feb 20, 2015 | 2:29 pm

Just watched that movie bus stop, is that a brill? Bus in the movie, lots of movie shots and footage in the movie. My 4104 dream is on hold for now, got to sell some stuff.

Kevin Lewis | Feb 26, 2015 | 8:51 am

Hey Tommi, my bus is complete but would make a good parts unit. Give me a call or an e-mail if you would like any more info. 570-702-6985.

Tommi | Feb 28, 2015 | 11:21 am

I can't afford Kevin's bus, but maybe a joint venture?
How many people are out there needing parts?
The one I'm about to buy is pretty much done up and just coming out of the shop, but I'd be interested in getting some parts.

J. Estep | Jun 23, 2015 | 9:30 pm

We bought a 4103 a few years back in 2013. Was in great condition and already coverted to RV. Does need front window and the bottom step does not pull out when opening door. She fired right up and we drove her to rv park about 60 or 70 miles from where we purchased from and lived in it for 6 months. It was a little cramped with a 3 year old. The speedometer does not work or the generator. And the roof A/C's need repair. It needs new tires. All in all, she a beaut. Not sure what the s/n is, but in due time we will know the ins and outs. We bought laminate wood flooring to replace the dingy carpet. Would like to get to know other 4103 owners, as we are looking for parts. Thanks

J. Estep | Jun 23, 2015 | 9:45 pm

What type license do you need to drive the 4103 legally, i live tx and frequently travel to florida

Mary Heiser | Jun 24, 2015 | 6:34 am

You do not need any special license as long as it's titled as an RV. The windshield is a problem!! We are trying to have bigger ones cut down and if that doesn't work we will have to go with lexan. Where did you find your 4103. My email is - we have had since 2012. It's fully converted. We also have to get the bottom step fixed. They only made 1501 of these buses - so there are not many left!

Jeff | Nov 10, 2015 | 8:55 am

We have a 1951 PD-4103 and are looking for either the long transit-style rear view side mirrors (std) or front end mounded round ("lollypop") style mirrors.

Charles Seaton | Nov 10, 2015 | 9:22 am

In New york, if the coach is registered o historic plates and is not used commercially you can drive with only an operator's license.
