62-65 A Bodies vs. 1968 A- interchange drivelines?

Quick question - I've been in the C Body game for quite a while but am looking at a 65 Valiant that needs entire dirveline. I have a low miles 68 Dart that I was hoping I could pull the 225/904 and 7 1/4 and direct swap. Will 68 Dodge drivelines swap/bolt in to a 65 Plymouth? Dimensions same, or did everything change in 66? Thanks - Andy
