Jeep Rear End

I would consider missing out on a Dana 35 as a good opportunity. That rear end is weak junk at best, not worth the mig wire to install perches on. They also have radio flyer rear brakes on them.
Get an 8.8 Ford from Exploder for $100-$150 which will have disk brakes, 5x4.5" or BBP and usually a limited slip. Ratios from 3.08-4.10 in 30 spline Exploder model. Look up sticky for info.
