Rebuild includes our special oil pump gasket, .007. and also includes machining of the check seats.
USA made Difference between the long and short rotor will depend on the model of your oil pump. There is a narrow pump that only has 2 bypass caps or the wide body pump which has 3 bypass caps. The 2 bypass caps would get the short rotor and the wide body pump would get the long rotor.
Please specify tall or short rotor. Short/Narrow Body Pump Rotor: Measures: .625 Tall/Wide Body Pump Rotor: Measures: 1.125
