PC:How often do you need a cam bearing tool. If only occasionally, I would think a tool rental place would have a universal tool such as the one NAPA had when I worked there. My tool is home made, the pucks are steel. Anyone with a lathe should be able to make you a puck to fit the Y bearings and the chev rod. Fortunately all 5 Y bearings are the same size, so only 1 puck in needed.
