SSBC Disc Brake Conversion Kit

I installed some on my 66 cuda easy install only had to open up two bolt holes to accomidate the bolts in the kit.However i bought some steeleys for a fourmula s with disks and they hit the caliper i smoothed out the top of the caliper but still rubbed added spacers and they were fine[i hate spacers]i ended up purchasing rallys and all is well no clearance issues.Also the rotors are drilled for both small and big bolt pattern so if you go to a big pattern rear, just exchange studs in the front.I have had them on my cuda for three years no problems very happy with their product.
