Please help. I am having problem with blinkers and I think it is the switch, however I cannot figure out how to remove the horn rim. It is the spoke type on a 66, Once I get that off I can handle the wheel if it needs to come off. So what is the proper way to remove the horn rim to get to the blinker switch? I have looked for a hidden screw or catch but see nothing. Don't want to break anything by just pulling or giving it a good yank! Son't see anything in the shop manuel about it, just says to remove but not how. Thanks
