Good question.
Depends on inner and outer spline count and diameter. So cant say fir sure without more info. Year to and from? Any carrier or other mods?
By beef up do you mean different metal or thicker?

Both axles would be stock 27 spline, stock ring and pinion. I street drive and play in the sand dunes other than that she sits in the garage. I just want to eliminate the 2-piece axle shaft and put a spartan locker in. Any help on the axle fitment would be appreciated. Thanks.
