I recently built a 14 bolt dually diff and in the process discovered 14 bolt dually and single wheel 1 ton/3/4 ton spindles are shorter by about 5/8" than the dually version. Since the 14 bolt design came from the Eaton it's logical to assume the spindle lengths would be different for dually verses single wheel configuration. I hope they are not, would save me swapping the diff case en lieu of just the hubs.
