Water pump is failing on my 1949 Chev Truck. The engine is from a 1954 Bel Air power glide. Ordered a Carter water pump from Rock Auto and thought everything was good. Started looking at the distance of the pulley from the engine and the width of the pulley that the belt rides in and it's different. Won't work. The bully width is wider than the water pump that came off the truck and the pulley distance from the engine is about 1/4 inch more, so the belt won't line up with the lower pulley and alternator. Looking at other water pumps from parts stores, I can't tell if they will work or not. How can I know that I'm getting the right water pump when ordering? These are supposed to be for a 1954 235 engine.
