EMPI offers this replacement hardware for Volkswagen oil pumps. The bolts are 40mm long, 8 x 1.25 thread pitch, and have a 10mm head. Each bolt goes through the oil pump cover plate, through the pump, and into the case of the motor. Hardware sold as a pack of 4 (enough for 1 car). These bolts fit all VW air cooled motors from the introduction of the 1500cc motor on. They fit 1967 to 1979 Beetle, 1967 to 1974 Karmann Ghia, 1966 to 1971 Bus, 1962 to 1973 Type 3s (Squareback, Notchback, Fastback), and 1973 and 1974 Things models.
