Wilwood Mopar A-Body Front Disc-Spindle Hub with Intermediate Rotor Plate (1965–1972)

This A-Body hub is listed for the specified 1965–1972 disc-brake spindle. It mounts a vented rotor through an intermediate plate, and its geometry should be compared with the exact Wilwood conversion instructions. Wilwood Engineering’s work covers the design and manufacture of disc brake systems for motorsport, street-performance and specialized applications. Bill Wood founded the company in 1977 in a business now based in Camarillo, California. Its calipers, master cylinders, brake rotors, brake lines, valves and fittings must be selected around the complete system.
