    Rated 4 out of 5 by from JEGS Brand Rocker Arms The rocker arm fulcrum ball fits very tight (too tight) over the rocker arm studs. Once on they are very hard to remove from the studs.....you will need to pry up on the rocker arm assy to get them off. My rocker arm studs are standard size BBC, 7/16" studs. This will not effect function, but the ID of the fulcrum ball should be a little larger
