Manual trans swap info

Thanks for all the info, that will keep me busy reading for awhile. Again sorry upfront for my stupid questions, but here we go:

#1 If I use the Napa bushing, will the input shaft of the trans need to be cut down as well?

#2 Does anybody have a part number for the Napa bushing, or the Ram roller bearing, or what years of Ram's the bearing will work from?

#3 I would love to have a 833 trans, but my money is on the low side... Could I use a three speed? I know that isn't desireable as it isn't a performance trans. But my 360 is basically just a stock rebuild, and I don't plan on beating on it or taking it to the track(my local track just closed). It will be more of a cruising car.

#4 Can the flywheel be from a Ram with a 360, or does it need to stay a a body unit?

Thanks again for all of the help so far! I appreciate it all very much.
