How does a rear Dana 44 (1983 Waggoner)compared to a 10 or 12 bolt Chevy? I have a friend that wants to put a rear disk set-up on his Yeep and he just bought a pair of Dana 44's fron a 1983 Jepp Waggoner. Anyone know? He was looking at the 10/12 bolt rear disk that A-Tron has and thought it might work. HELP !!
