www.sdori.com is who makes the front balljoint spacer. i actually contacted them and helped design them. i ran the pre-production prototype on myo ld 85 2wd. some 2wds had a 8" rear end. the housings were the same as the 4wd, except sprind under and 5 lug... most of the 2wds had a 7.5" diff though.. i had an 8" 2wd diff that had 3.07s.... i put in a third from my friends 86 4x4 runner with a 4.10 gearset... you can actually swap the shafts out without issue... width is the same between generations, 84-85, and 86-95 4x2 or 4x4
