Double check it. I know that on 68 and 69, the vent window is about an inch taller on the 4 doors ( of course the 69 2 door coupes don't have these ), requiring different weatherstripping. I'm baseing that on my attempt to put a vent window from a 69 4 door sedan (a pillerless 4 door) in my 68 2 door coupe. They evidently use a taller windshield too, cause the windshield molding wouldn't fit either.
