so im getting ready to throw some gears in my rearend and change out my diff. ive decided while im at it ima up my axles to a 31 spline mosers. i still have the drum brakes on the rear and want to eventually put a baer brake kit on. so my question is can i get a regular set of axles or do i have to get ones specifically for the drums and then swap them when i change to discs?
