Hey Dennis. I am not aware of the ring and pinion being any different. They should all be 8.2 10 bolt rears. Have you contacted an aftermarket gear maker? Richmond? What gears are you looking for? I think if you wanted a real steep gear ( more than 4.11s) you may run into a problem there. Sorry I could not be of more help, Kev
