i installed a new clutch kit with the motor rebuild.
My set-up is currently, 4.56 diff gears turning 35x15.5x15 TSL swampers. Welded rear.
Works awsome off-road, not so good on highway, needed either 4.88 or 5.29's.
If you are interested I have one set of Brand new 5.29's still in the box (Precision Gear) that I was going to use with the motor. I will throw them in for an extra $125.00 (you would still have to purchase another set for the front, I run a hypinion front diff).
