The windows can be bought here in Minnesota. I have a set in my car. They can also date the glass. http://www.autocityclassic.com/
I just went to this site. They show the same door glass to fit a Camaro and a Firebird. Don't see a thing mentioned about dating or Bird glass. So, how would one check out your claim ? Would it take a phone call or is there some way to find the info online ?
