1958-1968 CORVETTE WATER PUMP PULLEY REINFORCEMENT SPACER.

Water pump pulley reinforcement spacer. 1958-62 All, located under pulley. 1966 with 327/300 outside location between fan clutch and pulley. 1965-67 396 and 427 exc. P/S, under pulley. We recommend using this part on the underside of all 1963-64 models also. This will prevent fracture of the pulley’s center section. Press the water pump flange further onto the shaft, the same thickness as the reinforcement. This change is undetectable after installation.
