This Big Block bracket is designed for the Chevrolet non-metric power steering pumps with the attached reservoir. They allow clearance for the alternator belt no matter where the alternator is mounted. These pumps were used on most Chevrolet applications with short and long water pumps until the mid 1980s. Pumps with single or double groove pulleys will work. Short water pump applications are normally driven off an available fron Chevrolet under Part Number 3751232.
