I sold a 67 Camaro (what was left of one) over ten years ago, and I just found the back glass for it under my house. I wanted to know what it's worth. It's etched at the bottom center- Safety flo-lite, as-2, solid tempered, m72. Any help wuld be appreciated. Thanks.

 

That is an original GM installed glass. M72 is the model number; 3/16" tempered glass, no tint.
New repro glass can be had for $150~175 delivered. If yours is in perfect condition, it would be wanted more by someone who is doing a "correct" restoration. Between $200~300 would not be out of line. Might want to try selling it on ebay, but I would want to try and sell it locally to avoid having to ship it and have it get damaged. Craigslist would be another good place to list it. On Craigslist, start your price in the low $300's.

 

Thanks for the help. It has a couple small chips on the bottom edge not seen with trim i'd say. I'm with you on shipping it, id rather sell locally too. Thanks again. Much appreciated!
