Rebuilt power brake booster for the 1971-73 Mercury Cougar and Ford Mustang. All Cougars and Mustangs used the same 9501 Bendix power booster, but the internals of the booster changed in July of 1972. 1972 cars manufactured after 7/72 used the 1973 booster. Because of the improved internals, all of our 1971-73 rebuilt boosters come with the 1973 internals.
Replaces Ford Part # D1ZZ-2005-A, D1ZZ-2005-B, & D2ZZ-2005-A.
