35 spline axle shaft
 

Has anyone made a 35 spline full float rear axle shaft for the M715 to be able to use a selectable ARB locker?

Have you seen this page?

That what it takes to do a 35 spline swap for the front axle...might give you ideas on how to work out the rear...dont know that anyone has done one of those yet...
