as far as rear stuff goes, richmond makes a good gear set, as does motive gear. i have found the motive gear stuff to be fussy as far as set up.
they seem to like to run on the higher side of the backlash spec. noticed this mostly with the ford 7.5 gearing.
motive gear makes a master kit, that includes the gear set, all bearings and seals ring gear bolts, and shims all in 1 box.
had good luck with drive train components stuff as well.
feel free to send me an email for help, parts, or whatever.
good luck, have fun!!
