I cant seem to find out what size the bolts are on the connecting rod end caps. They look like it needs a spline socket but what size and were can i find some? I called some places and they dont have them. Thanks

They require a 5/16" - 12 point socket. It has to be thin-wall to clear. Many are not thin enough. Mine is Snap-On. I also have a Craftsman that works and a Craftsman that does not work.
