I don't know, but I've been told that the disc brakes should be to the front of the spindle. Mine were in the back. I think all you have to do is reverse the spindles L-R side and R-L side. How does that affect the alignment?
stock the 73-up brakes came witht he caliber in front. but the spindles can be switched side to side to put the caliber in the rear with no affects on alignment. just be sure to use the proper brake hoses.
