63 doors have a different latch, but are dimensionally the same as 64-66. 2 and 4 door sedan and 2 door ht. doors are all interchangeable between
Dart and Valiant/Barracuda. Trim is different between years and models. I believe there is a slight difference in rear doors for early A wagons. I have
also been told this applies to B body wagon rear doors as well.
