I broke my rear for the 6th time now.. 3 gear sets and 2 posi's 1 axle.. 2nd gear set with the new motor.. with the 4.10s I made a flat space in the ring gear and now I rounded the pinion pretty much all the way around on the 3.73s. I plan on upping the boost and making a few more mods to my car... will a 12 bolt hold? Im going with a posi as this is my daily driver, no locker or spool.. So 9" or 12 bolt??


Thanks
Nick
