first thing i'd do is get my hands on an axle to start. i don't know how popular toys are in nashville but around here
, it's hard to find yota axles. you can pick up a complete axle swap kit from Marlin Crawler, Trail-gear, All-Pro, etc. with everything you need to do the swap(with the exception of the axle and driveshaft). i built my 88 up pretty much how you described but like i said, find an axle first. after that, everything else will/should fall into place.

SAS88TOY, caged, lockered, Longfielded, etc. etc. etc. blah blah blah!!!
