One more question on axles. If I wanted to swap in a pair of Dana 44's from an SJ into a '74 CJ, would I HAVE to narrow that axles? It looks like the SJ is 58 inches wide, the CJ is 53 inches wides. that is only 2 and a half inches farther out on each side (which wouldn't hurt my feeling being a little wider). Is there any reason that that wouldn't work? I would have to move the spring perches, would that interfere with the diff housing?
