guess what i found!

i was looking through the atlanta advertiser today, and i found a set of 14" rally wheels w/ rings and caps for $300, AND i found a 4 speed tranny out of a '64 dart for $150...
i was like "GAH!!!"
could i use a 4 speed from a 64 in a 70s model a body? besides the tunnel hump and the clutch pedal jive... would it be usable?
not necessarily my valiant, but a 70s model A body...
