Who knows glass?
 

Does anyone know what the different shape of the door windows on a '68' coupe, fastback and convertible is? MY coupe had a passenger side window that was sloped down about 1/2 an inch on the top of the glass where it met the rear window. Would this window belong in a fastback or convertible?

I just went out and looked at my 68 Fastback in the garage. The door glass does go down in the back. How much???? I'm sorry I don't know. I don't have a coupe to compare it too. But, I would guess that it is a Fastback glass, since the coupe and convert. both have rear windows.
