I am rebuilding a 73 CB500 Four and am hoping to wrap this project up shortly. I have resleeved the jugs, put on the bigger pistons, cleaned everything, and painted the head. Everything is ready to be put back together except I need new cylinder studs. As far as I can tell no more exist and I've been looking for well over a month now. I was wondering if anybody happened to know sometihng that would work as a replacement so I wouldn't have to go match these up myself.
