[muddyole 69]

Looking for a locker to finish up the rear going into the short bed anyone have one out of a pickup or van etc that they are willing to sell or trade for ? prefer 31 spline would consider a 28 spline locker I am under the impression that the 31 spline is more common in trucks etc I have a set of 31 spline and a set of 28 spline axles and can/will use either one thanks Mike
