Its been done to Dart hard tops. Some use parts from a later model car. Others change entire door along with the later model weather stripping. There was a Dart shown in a recent thread that had been changed ( oldmanmopar maybe?). All Darts and verts have a very similar flat line at their roof. If they were exactly the same they would have the same part numbers, so there is some difference. You change adding wind noise.
Cannot be done to B'cuda notch back though. Probably not fast back either. There isn't a late model door glass with correct shape.
