if u can find toyota parts....
toyota truck front hub swap detailed on this forum, as well as Mmax LSD options/sources + 3.54 starion gear swap
when rearend shopping for my corolla, 92 toyota pickup diff was only 1" wider. Mmax ~2.25" wider
so toyota truck diff ~1.25" narrower than Mmax. If u can find one LSD, u get the popular 5x4.5" pattern as a bonus
