Tim pointed out the gasket set if you want to order it. But I would just cut it out of a sheet of 1/16" rubber, maybe even an old inner tube. it is 4.75"od x 3.125"id or a tight fit to the motor. The metal retainer ring is 1/16"tk x 4.75"od x 3.75"id. it is retained by three clutch head screws from the engine side.
