8 3/4 rebuil ?

The factory mopar 8 3/4 units with the clutch packs are rebuildable, made from 1959-1968, also known as power lock, sure-grip or clutch posi. These are pretty tough units and can hold up to plenty of abuse. You can buy new ones but they can get pretty spendy. Also try Randy's Ring & Pinion, they have all kinds of great parts for chrysler rear ends! I would stay away from the newer factory mopar cone style limited slip units made 1969-74. These burn up way easier, especially doing burnouts around corners. They are also more work to rebuild. All aftermarket ones are probably good enough, you can also get these right from the mopar dealer! :thumbup:
