No no no, I just gave the condensed version. Ok, to be fair: All 8" thirds are interchangable, doesn't matter if it's v6 or 4cyl. The fj80 fronts were hi pinion, that's all. Yes it will matter cause you don't wanna run a hi pinion third in the rear unless you like constantly replacing parts, but you can run v6 thirds in either end. Typically the way people do it is hi pinion front, v6 rear.
