Thanks for the information, I took my CL77 ignition switch out yesterday and compared them and I see what you are describing. I think I'll go with your advice and try to look for the correct ignition switch. I took some pictures of the switch and fork lock that I have and I'll post it here in case anyone is interested in it.
