I am wanting to put 99-04 disc brakes on my 93 gt. I have the brackets from North Racecars to mount the calipers in the rear. What else do I need? I also have the spindles from a 94 v6 mustang. Besides the front and rear calipers and the caliper brackets that the calipers bolt to, what else is there? What do I have to do to make the clear and work?
