Im planning on installing the rear disc brakes from a 1994 Crown Vic on my 65 Mustang. I plan on buying the needed spacers that you see on ebay to make the conversion. Ok my question is, do i have to remove the Axel shaft from the diff in order to install the backing plate that comes from the Crown Vic? Can someone help me out on this one, what do i have to do to remove the axel shaft
