10 spline should be a 742 no crush sleaves
Yes sir you are correct, but there is nothing stock about that rear end. We have strange axles a 4.88 gears which had to be shimmed because of the monster ring gear. So there is one in there.
To drive it on the highway i have to get another 3rd member, something that will gove me a 2,000 ish rpm at 75. Im guessing something in the 2.70s or 2.80s. The 35"s will lower it more, ik there are calculators out there to figure it out.
