i just swapped the full size axles from a 79 ford into my jeep without much problems. i also did a soa at the same time and beleive it or not the front dana 44(soild tube) perchs bolted up with a little reaming of the center hole. the rear ford 9 inch 31 spline, required the movment of shock and spring perches though...wasnt too much work. i would post a pic but i dont know how. if you give me yoyr e-mail i can send you some.
