I have a Dana 35 with 4:10 gears out of a YJ. It's in great condition, Brakes and wheel cylinders have less than 10,000 miles. Axle seal changed at the same time. This is a ready to bolt in rear end, complete with e-brake cables, drum to drum. I only changed it to install the 8.8. It most likely has 150,000 miles on it.
