Autocar glass removal
Print Topic | Close Window

Hi all,
I'm restoring a 66 DC87, finally have the cab off and planning to get going on it. My plan was to have a local glass shop remove the windshield and rear window glass (all the glass is good) so I can clean up that area and maybe soda blast it, then re-install when I'm done. The local shop though won't guarantee they can get them out without breaking them. I've read the past posts on cost and scarcity of glass for that age Acar. Anyone had any experience successfully removing glass or am I better off just leaving the glass in and working around them?

Leo, Don't know the answer but I do know all glass shops will tell you the same thing if you ask them to remove or install a used piece of glass. I would think they should be able to do it but that is me thinking. Lot's of A-CAR guys on here so you should get an answer soon. Wayne

Are you planning on trying to reuse the rubber seals?  I'm not familiar with your truck specifically, but if you don't need the rubber you should be able to remove them yourself, the seal should be able to be cut away so the glass can come out easily.  I removed the glass from my Internationals that way without a problem.  Just take your time, and perhaps have a helper there to make sure it doesn't just drop out and break.  Like most things in life patience pays.

I know it would probably be expensive, but there are companies that do custom glass(used for custom cars, limos, etc).  I'm not sure if they can do compound curves or not, but I know they can do curved glass.  Just a thought if the worst does happen

I read maybe on this forum that windshield glass for the Corporate Cab (Autocar,White Diamond Reo,+T ) pre 1969? is hard to find. The post I read said you can use glass from 1970 up just have to get it cut to size. Does anyone else know anything more about this? If so it would be a big help to those needing windshields for pre 1969?. Joe D.

The flat rear cab glass is a no brainer if it breaks removing it. The Acar Drivers Cab windshields are just about none existent. Real spendy if you do obtain a set. 68 and above Corporate Cab windshields are getting a little scarce also. You can cut them down to fit, trick is will your glass house do it?

Remove the center divider, then, if you plan on using new rubber channel cut the old one away from the glass and push out from the inside of the cab. The rubber channel is available from several suppliers. If you are very careful, they will come out in one piece. Use them as a pattern to cut down the larger glass. I've had several cut down, but be prepared to lose one occasionally. I seal the edge with clear nail polish and let it set-up. This will help preventing clouding on the cut glass edge. Reinstallation is a reverse procedure, but don't use RTV as a sealer.

Hope this somewhat helps.

My only direct experience with Autocar windshields is with a 74 model.  Older literature touts the fact that for emergency exit, push out on the upper outside corner of the glass and it will come out. 

The rubber gasket will have a lock strip on the exterior.  Pull it out or release the strip and remove the glass.  The new gasket is available in bulk from a good glass shop.  Cut the gasket a little longer than the pattern as it will shrink and leave a gap.

The taller windshields can be cut down according to some glass shops.  The 74 windshields were a stock item made in Mexico.

We loaned out our shop manual-can't seem to get it back.  Maybe someone can post the replacement procedure and save a lot of heartburn.

I asked  my local glass shop if they can cut curved glass and they told me that its difficult to get the curve right and there's a membrane in between the glass thats hard to cut without wrecking.  Is this true?? I'm lookin for glass for my 1978 White Western Star (small windshield). I was askin if i had to get the bigger glass from the 80"s model cabs if it would work.

I don't have anything with the corporate cab any more but I am really surprised that this glass is no longer available. there is still a lot of those cabs around. Wayne
By steelcowboy - Monday, November 21, 2011 4:24 PM
they said they had to do some searching around for glass but  should be able to find it. I  needed the measurements and didn't have any with me at the time
By dashby - Monday, November 21, 2011 7:22 PM
Check for a 78 model DC Autocar--should be the same for your Star.

The membrane in the middle is a plastic to keep the glass from shattering in to shards (safety glass).  Can cut with a knife (I think)

Would suggest a different glass shop if they don't know how safety glass is made--obviously never cut any.


BTW--As I understand, there are 3 sizes of windshields for the "corporate" Autocar cab.  ALL info is approx.--50's to late 60's=short---70's into early 80's=medium heigth--80's to end of production=tall heigth or High Hat cab.  This applies to doors--not sure about windshields.

Maybe someone will post that knows more about this than me--Rick?--Diesel Doug--anybody?

I have an 88 Star cab--As I recall, the windshield was the same as my 74--Confused yet?

McMaster has the seal. Part # 3275t22. I also have heard that you can cut the taller one down but don't know of anyone who has done it. I've also heard that you can part the plastic membrane by applying lighter fluid to the joint and lighting it. The solvent softens it and heat melts it so it will pull apart. Haven't seen it done either.

Here is a link to a hod-rodder who used sandblasting to cut down his windshield.

Seems to me that it should work alright, but I have not personally done it nor known anyone who has personally done it.....If I ever need to do a cut I will give it a try.

We had new windshields cut down for our '66 Autocar about 6 or 7 years ago. The windshields have the same contour, they are just different heights. Dunellen Auto Glass, (732) 752-5740, in Dunellen, NJ, did them for us. They made a pattern in case we needed more in the future.

My local glass shop here in Harrisonville got me two windshields for my 72Western Star. I got the new rubbers and they installed both for $260. That included taking them back to their shop and adding a little more curve to them. I'm not sure about the pre '69 models but Sante Fe Glass had them for my '72 the next day.

From my experience, the installation cost was a good investment.

Bet you guys do a lot of business with this shop??

I would agree with this. Nobody could gaurantee that the glass will not break. They will most likely have the experience and tools to do it better and safer than you could do it yourself. Go with your first decision.

That price included the glass. They do all our glass work and come to us.

Does anybody know if this is true? Somebody told me that the left and right '60s class was the same piece, just had to be turned over.

I know I have removed more then a few 9670 windshields without damage, only on one did I have a small crack when my helper got a little to aggressive. Slow and sure does the trick, don't be  in a rush, and make sure you have a handle on the glass at all times.
By FBHOMER - Wednesday, November 23, 2011 8:57 AM
They told me that there is a left side and right side. I thought the same thing too.
By Dieseldoug - Wednesday, November 23, 2011 3:06 PM
They will not swap... Two part numbers, and two pattern numbers for the windshield makers.

1950 to 1967 Drivers Cab    18" tall   558240   or   849557      Glass Left Hand tinted  “1950 thru 1967“      pattern no.  594
                                                       558241   or   849211      Glass Right Hand tinted “1950 thru 1967”     pattern no.  595

1967 Late to 80s Corporate cab    21 1/2" tall    Left Tinted   Pattern No. 694

                                                                      Right Tinted  Pattern No. 695  

The glass outfits will use the pattern number rather than the factory part numbers.

If someone finds a source for the 18" glass , LET US KNOW. there are a bunch of us that could use them and possibly obtain lower a price on getting them made.

The 86 Western Star windshield is apprx. 2 1/2" taller than the glass from our 74 Autocar=21".  Measured today.

We paid apprx. $110 ea.--carry out.  This was about 2 years ago.

I can be added to that list, my windshields aren't cracked but the fog has taken over almost 1/4 of each windshield.

I recently saw a product that claimed it could fix fogged automotive windshields. Anybody else?

i just tracked down and bought a windshield for an '80 DC9964.  i'm doing a restoration, and i'm not at the windshield replacement point, but thought i'd better act on it while they're out there.  safelite tracked it down, and i also found it through another source.  the seal(rubber) apparently is available from westfall gmc in kansas city.

i'll give you references for this stuff if you need them.

best of luck

I looked at my 67 A7564T and found the left and right halves to be different. The bottoms of each side tilt downward towards the doors making the left and right not interchangeable.
