Installation of the Cobra brakes also enables owners to install 17-inch wheels from any ’94-’04 Mustang, including the popular Bullitt-style wheels. Designed to work with all drum-brake cars with 8- or 9-inch small-bearing rear axles, the Vintage Venom kit includes billet aluminum adaptors for mounting the late-model Cobra calipers on vintage drum-brake spindles and axles, rotor adaptors for utilizing Cobra rotors, and all mounting hardware.
