I put a set of 1982 Wagoneer axles under my 1976 CJ7. The Waggy axles are 4 inches wider and I found a couple of sites that showed how to outboard the springs. I'll try to find them for you. I also put the Waggy power steering, 727 auto tranny, and 208 transfer under it. The front is a 44 and the rear is a 20. I Know, "OOh, A 20!" But this baby came with one piece axles and the tubes are bigger that the CJ7's 20 tubes. I love this set up. It drives great and handles like a dream. I have a J10 that has a 400 Turbo and both 44s that I'm hoping to put in something one of these days.
