Hey guys I have a 1957 chevy 3100 with the 235, I took the fan off and discovered a crack on the water pump pulley. The crack is a complete circle surrounding the bolt holes. The truck ran fine with it just the way it is, but I would really like to put a new pulley on but can find one anywhere. Anyone have an extra one or know of a website? All I can find is 7" pulleys for a SBC.
