You can get a complete kit from Quad4X4, Dan is a good guy to deal with. The kit has everything you need, Brand NEW Trans, South Bend Con-O clutch, flywheel, transfer case shifter extension, and the back-up light extender, and the plate to mount the trans to the crossmember. All you will need to do is shorten the rear driveshaft and lenghten the front about 5-6". You have to mount the crossmember farther back, they're is supposed to be a 2nd set of hole in the frame, although I have yet to see them on mine. No big deal, I can drill holes all day. I'm doing my 01 in the spring.
