63/66 Valiants

Post #3 is excellent. I would add that some parts are the same for all Mopar bodies of the same year. For example, the door handles look identical in my 1965 A & C bodies, as are many electrical parts, including the bulkhead connector (I think). But sometimes even the same year and body don't interchange, like 1964 front fenders vary between Dart and Valiant, as do the matching fwd splash shields. Convertibles and 4 doors add to the variances.
