I'm trying to figure out my gearing options after I find a complete e-locked rear. My truck has 3.91's, not common with the elocker I think. I live in san diego, home to a dearth of TRD prerunners, does anyone know if these commonly come with 4.30's. I'm fixin' to harvest a prerunner rear and then re-gear my front, either by new gears or by finding a matching diff out of something else. Are all the ADD front diffs compatible 95-04 (can I bolt on a front diff from a push button 4runner or tacoma to my manual transfer cased(ADD) tacoma?
