Plymouth doors also same, as far as I can understand.My Mitchell's Collision Part # guide shows the the doors, vent window frames and glass are all interchangeable between convertible and hardtop.
Convertible doors usually have a wedge on them that works with a corresponding piece in the door jam to help eliminate shimmy in this area. These will have to be transferred to hardtop doors if working on a convertible. There will be a couple of factory supplied divots on the door to indicate where mounting holes need to be drilled.
Maybe so, I have a set off a hardtop and a convertible and thenones I have are not the same.Parts manual shows that vent window glass and frames are the same, whether hardtop or convertible.
