I posted a couple pics on page 1 of this thread. After driving it i realized that the larger rear at the stock pinion angle does place the driveshaft vertically closer to the tunnel than the 7 1/4. Side to side is not an issue, but on big bumps heavily loaded the driveshaft will strike the tunnel. I plan on modifying the bump stops, which are currently useless. I believe the 8 3/4 bump stops are longer but I’m not sure.
