Installation Notes and Tips

Verify drum diameter, bolt pattern, center hole diameter, and overall height before installation. For 1968-1973 Ford Bronco applications, confirm chassis number requirements, and for 1968-1969 Ford F-100 applications, confirm the full cast and 3.09-inch overall height specification.
