Ok.. Need a little help here...changing out my sons old drums for discs...His is a 1974. I traded some 71 doors for what the guy told me was 1968 Mustang 428 Cobra Jet Bullet Car Spindles, Rotors, and Calipers...The spindles appear to be exactly the right pattern to interchange with his old drum spindles. Can anyone verify that these will work?? And I really need some brake hose lines now to go from calipers to main lines that match.
