A Ford 292 pulley will fit also. I modified my own pump buy buying a rebuilt unit from Napa and shortening it by pressing the hub down and cutting off the excess shaft. It's best to practice on your old pump first, since you only get one shot at it unless you have a bearing splitter to press the hub back the other way. It only takes a couple tons to move the hub on the shaft so you should be able to do it with a bottle jack against the frame of a truck and a deep socket or length of pipe to fit over the shaft if you don't have a real press. Mine cost me $30, I ate the core charge of $5.
