I am looking for the part numbers for front and rear Bocca bearings for a MAC 21.
The bad news - Last Sunday the bottom skirt in the Jim Wilson CMB 21 Greenhead in my Jim Wilson Sport 20 broke and scattered metal pieces throughout the engine.
The good news - Mark Anderson offered me his MAC 21 that he no longer plans to use and suggested the bearings be replaced before it runs again. This will be a much less expensive alternative compared to purchasing piston/sleeve/head and bearings for the CMB 21.
Gary Preusse has Bocca bearings, but doesn't know the part number.
Thanks for the help,
JD
