I gotta run into town to take my aluminum rims for new rubber and figured I would pick up some bolts to mount my Mac 4-1. The bolts holding my Kerker on are not gonna work......they are countersunk Phillips head bolts....the flanges on the Mac are just slotted. So Im gonna need to get some regular Hex head bolts.
What size are the flange bolts....M8, M10, M12 ?
