I haven't tried to swap the '63 motor with the '64-up motor but the obvious difference I see is the length of the wiring pigtail.

Uh…the entire mounting system is different. The '63 motor bolts onto a different place, and so its gear housing and mount casting is very different. That's why '63 wiper motors are one year only.
