I forgot to mention that you should buy and use a steel cap on the drivers side of any 8 3/4 that will get abused by spinning tires that hook up quickly while spinning
8 3/4 ring gears get cracks in the outer edge of the teeth that eventually break off and fall into the rear end ending up getting jammed between the ring gear and pinion gear breaking both gears in a major way, which can lock up the rear end momentarily, NOT GOOD
Good luck on your car and decision
