63-70 Chevrolet pick-up truck front and rear disc brake conversion kit with booster master. What makes this kit special and hard to find is that it is available in 5 lug pattern or 6 lug pattern. This complete kit includes the complete front disc brake kit, rear disc brake kit and the power brake booster master combo. Easy to install, the kit bolts directly to the spindles and rear axles housing without major modification. We made great effort to insure the rotors, calipers and pads were all going to be a late model Chevrolet style available at your local parts store.
