Any FJ80 from 1990-1997. Some had electric front lockers, others were just open diffs. If you get an open diff, any standard V6 locker (detroit, arb, etc...) will work. If you want to run a lockright or a ez-locker or an aussie locker, you'll need to find a V6 rear diff carrier and install the locker in that, then drop it in the hy-pinion housing
