The 58 I'm working on now already has them on it but I am redoing them. The calipers are mid 70's full size & intermidiate cars. I got new ceramic pads & caliper kits. The rotor,s are 11 in. from mid 70's intermidiate. It has a 4 3/4 5 bolt pattern. If you are going to use 5 hole wheels I would get a kit with the brackets, spacers, bolts, & brgs. with spacers & scroung the rest. If you want 6 hole wheels you would probably just buy the whole kit. If you want me to send some photo's I can but it will be Tues.
