Unless you plan on beating the holy hell out of the thing (speed-shifting or power-shifting) and/or you're going to be running an ungodly amount of power ahead of it, you might just be better off finding a 4-cylinder T-5 and just using the different pilot bearing. Better 1st gear in those, they're plentiful, and they can be had for dirt-cheap.
Also, don't forget the block seperator plate and flywheel bolts on your list of parts for the swap.
