If pre '68 dave's info is correct, Buffalo Steve can make an adapter to go between the bellhousing and transmission. Clutch choices might be seriously limited. I do imagine the swap would be similar to swapping a T5 in a deco truck. There are some great writeups on the deco truck swap in the tech section. I have never had a 32 truck, and have never compared the transmissions with the deco trucks, so my info is not 1st hand.
