I am new here hoping to find some help on the rear glass installation on my 1946 Chevy truck. I purchased new rubber for the rear glass. What I bought is the same thing that was there but new. I had a glazer come out to do the install he has done a lot of work for me in the past. He has 24 years experience owning his own glass shop. He could not figure out how to do the install. He said that it’s not the right thing. I have checked my part to make sure that I got the right thing. Couple sites that I looked at show exactly what I have. They want 450.00 to install new glass with what he says is the correct rubber seal. My original glass is slightly discolored and has some minor delaminating issues but I don’t want to change it for a new piece I like the patina. I have searched for any video showing an install on a 46 Chevy pickup and cannot find anything. I am hoping that someone can direct me to a video on the installation. I am very close to having my truck finished up. I have a few little minor things to do for completion. This window has been a real pain. If anyone can help me or offer any solutions it would be greatly appreciated thank you
