no the frames are different.
The 2 door sedan uses the same windscreen angle as the 4 door.
The coupe windscreen angle is laid more flat, therefore the different door frames.
You can use a coupe door but cut the frame off and attach a 4 door frame, but youll need to weld in an extra length for the width of the door...as the 4-door doors are shorter. Does that all make sense, sorry but Im a mixed up Skippy the bush Kangaroo...still on a high from yesterday race practice.
