I would think they are the same. Plymouth A bodies would be different.I have been told the rear wheel opening on Darts from 63 to 66 are the same, I'm looking for the wheel opening trim for the rear, can I expand my search to include these four years?
I would agree they are all the same shape except for wagons which had a fully radiused rear opening. Unsure if trim is all identical. don't remember my '63 GT having the stone guard like my '65 GT did at the front of the rear wheel opening. PLenty of pice on here or the Net to compare that would answer that question.
