I bought an Oil Filter Adapter to convert from the canister style OEM filter to a Baldwin filter but when I ordered the adapter it didn't come with the large bolt that goes through the center to hold the adapter to the motor. Does anyone know what diameter, length, and thread pitch that bolt needs to be? I have called everyone including the person I bought it from and no one can give me a straight answer. Thanks Truck is a 1986 M939 NHC 250 small cam non turbo.
