Small Block Ford Product Description:

Small Block Ford
Due to the large variety of timing cover, water pump, and pulley combinations used on Small Block Ford engines, we designed this bracket.  The compressor can be adjusted front to rear to align with the water pump and crank pulleys. Bolts to driver's side head. Will fit 289, 302, and 351 Windsor Engines. May not work with Serpentine Belt Setups.
