Sounds like a whole lotta work for a half-ton axle. One question though, if you're going to get custom shafts, why does the current bolt pattern matter? Wouldn't you be looking in to a disk conversion of some kind? Seems to me you could pick whatever axle you want, narrow it, get custom shafts with the 5 on 4.5" pattern, and adapt Explorer disks to it. :hmm:
