Hi guys I have got to the point of installing my glass. I have struggled with my back door glass in the panel truck all day. I think the glass is too big. The rubber is from Dennis Carpenter and the glass from Bob's classic glass in Oregon. The rubber seams to fit in the doors OK but when I load the glass and use a string to help pull the rubber over it gets stuck at the top. I broke the glass so i had nothing to loose so I put my foot against it and it still won't push in far enough to get the rubber to slip over flange. Any tricks before I break all my new glass. Thanks -Ed
It was many years ago that we replaced the window in my sons Jeep. But we had the same problem. In our case we were using to large a dia string. Remember the string is taking up space where the glass needs to be. It seems to me that we bought some 80 lb or 100lb braided fishing line. It was small in dia but wouldnt break. But now you have to be careful not to let the string cut into the rubber. We also used a pretty good amount of a spray silicon lubricant. We/I am no expert and we had a lot of the same problem you are having.
Thats the best I can do. Good luck.
There is always that nagging question in the back of your mind..does the new glass have the same dimension as the original..
..also, is there a very slight difference between each rear glass...maybe a slight taper on one side..you could make a paper pattern of the original if it's still available and in good shape..
..slightly dilluted dishwashing liquid soap, thin STRONG string,a good friend/helper, alot of patience and some cold adult beverages to consume between multiple progress evaluations may help..Good Luck!
I also broke my back glass trying to install it. When I went back to the glass shop for a second one, I ordered it 1/8 inch smaller...problem solved!
I'd suggest you fit the glass without the rubber. I don;t know how much smaller it should be but I imagine 1/4" all the way around would be a minimum. The rear didn't go into my 54 without a fight, and some cutting the rubber with the string but the windshield when in easy.
I don't have the original glass to see if they are the same. The glass is about a 1/4" over the flange all the way around when centered. I think that the problem is there are not many panel trucks out there and therefore they may not have had the oppurtunity to perfect the shape of the glass on real trucks. I'm thinking I may take the broken piece I have to a glass shop and have them cut me one 1/8 smaller all around and give it a try. I don't believe that back glass was safety glass back in 1948 so I might have them make it in plain glass.
I ordered glass from that company and took it to a glass shop to have it installed. The guy from the glass shop said it was the worst cut glass he had ever seen. It was 3/8 of an inch too big in several places. He cut the glass himself from flat glass and told me to send the glass back to the company and get my money back. I would never buy from them again. You can have it re cut or ground down to fit but I would just send it back.

The original glass would have been a safety plate, laminated automotive glass. It is important that you put the correct automotive glass back in. There's a reason safety glass is mandated. Any glass shop willing to do the work can do the job of creating and cutting the glass as necessary from the proper material.
As for sending it back, I can't because I purchased last year. I am hoping that the windshield, window and vent glass will be better since the box says JRD Internation Vintage Auto Glass on it. I saw that name on box of glass that was used on Overhaulin'. I thought if it was good enough for Foose then it should be good. When I ordered it, the guy I spoke with siad that it was going to come in to shipments, because he had to get it from another warehouse. The piece I tried was broke in my house by accident. I thought i would give it try to see how hard it was to get in. I figured I had nothing to loose because I already broke it. Well to say the least I broke the Hell out of it trying but it is at least 1/8" too large all around. How much glass should cover the lip when cetered in the opening?
This is the good peice I have left. I have the bottom of the glass resting at the bottom of the lip and next picture shows it's about 1/4" resting on the top of the lip.

you should be able to look at the gasket sort of cross section like to see how much in front of and below the metal flange the glass would sit.
it SHOULD be slightly larger than the metal frame so it can't be just pushed in to knock out the window from the rubber gasket.
The windshield should be a known entity since the panel is the same as all of the pickups. For the back glass, make a cardboard template & make sure that the glass is around 1/8" smaller all the way around. I posted this thread a few months ago for windshield installation: https://www.ford-trucks.com/forums/1...tallation.html
You have to be really careful when you push on the window...you need enough force to keep the seal going in, but not too much or the glass will crack.
Thanks Dan. I'm thinking I might cut a piece of thin luan board about 1/8" smaller than the glass I got and give it a test try. If too big take another 1/8 off and try again. Should the glass be smaller than the opening? Because as you may be able to see in the picture it is darn near a 1/4" larger all the way around than the opening flange.
