That is becouse I made the list for Dad, As his FZJ80 has the original Friction Plate L.S.D. in the rear. If you don't have the L.S.D., It's the same as the front.Nice list. The rear diff on FZJ's doesn't spec limited slip fluid, however. I've always used 75w-90 in the diffs/TC year round - any worries with that?
