Product details
A 0.8125-inch reference bore identifies the outer cone used in Wilwood’s specified 1941–1956 Packard conversion hub. The component supports the outboard end of its matching front hub and must run against the race specified for that assembly. This component comes from Wilwood Engineering, the disc brake manufacturer established by Bill Wood in 1977 and based in Camarillo, California. Its design and manufacturing range includes calipers, brake rotors, master cylinders, valves, fittings, and brake lines for motorsport, street-performance, and specialized applications. Selection depends on the requirements of the complete brake system.

Fitment & Compatibility
The Packard application in DS-719 uses hub 270-12730 with outer race 370-12732. Verify the installed conversion hub and its bearing pair before servicing a 1941–1956 car; chassis year alone does not establish the required bearing.
