Hi cudamark,
Thanks for the response.
I'm actually working on a '63 Dart 4door wagon. Haven't started the front doors yet. Looking forward to that trip. The rear doors are my victims. I feel like an idiot since I've done several Chevy doors with no difficulty. I'm wondering about that fixed glass behind the rear door glass. Since it's fixed the rear channel won't move much at all. Front one moves very little as well.
The factory did the assembly, so seems that disassembly would be straight forward. I'm unable to rotate the glass for making the part more narrow. Won't come close. I did remove the window regulator for cleaning and lube. That didn't help. Guess I'll piddle with it for awhile and use all of my naughty words.
