Jim,
I swapped a 3.7 into my bugeye for a few months and went back to a 4.2 when
I switched to a five speed. The only thing you need to do is swap out the
'pumpkin'. Pull the axles out just far enough to free it up, pull the bolts
out and remove the brake line mounting bolt. Clean/paint the new
one(optional), put in a new front seal cause its cheap to do now and a pain
to do later, lather on the gasket sealer and bolt it in. Push the axles
back in, (with new o-rings, seals, and paper gaskets), bolt up the drive
shaft and away you go.
Then begin to put a few bucks a week into a jar and find Paul A's phone
number for the day you get tired of the noisy ribcase and go for the five
speed. Careful browsing at the local pick and pulls can get you a good
Datsun tranny for under $100. Good luck.
