I know chargers are different, and some runners and GTX's have a steel mounting plate rather than aluminum. from what I can find all B body hardtops take the same glass. I need to get some reulators but it's hard when you're not sure what will interchange.
From what I got with my car they're the type with the large aluminum plates, for some reason the original owner took them apart and lost half the parts. I can't imagine why mopar decided to make such a complicated abortion just to roll up a rear window but here I am.
