Modern A-body glass?

I posted a similar thread several weeks ago without a lot of help. I have found a glass shop that has done a lot of Mustang and Camaro's and said it will require adding an extension to the pinch weld. He said he had black molding that can be cut to fit. I will be going out to talk to him in detail when I get to that point. A good starting point is to find a glass shop that specializes in custom rods.
