Fitment & Compatibility

DS928 identifies 1965–1967 Mustang V8 disc/drum spindles and 1968–1969 drum spindles only. Confirm the equivalent specific entry for the other Ford/Mercury models. Measure wheel and tire clearance with the 0.25-inch outward hub change and full caliper envelope. Hydraulic lines are separate, with production-year routing and master-cylinder pushrod requirements checked before the complete brake system is assembled and tested.

Match the individual model, year, submodel and brake configuration in the fitment table below.
