Fitment & Compatibility

The factory disc-brake spindle is essential on these listed Ford and Mercury applications. DS-1449 documents the 1970–1973 five-lug Mustang arrangement; the chart below adds individually specified Fairlane, Falcon, Ranchero, Torino, Cougar, Cyclone, Montego and Comet applications. Observe the 1970 Mustang GT350/GT500 exclusion and every year-specific row. Hubs and bearings accompany the brake kit, but spindles and hoses do not.
