Arthur, I have had the 7 prong switch and plastic cams out of the ignition but I still have trouble getting the key in and out, and putting the cams and plug on the end make it even worse. There was a post inside the cam thingy, that sits down over the end of a coil spring, and 1/2 of the post was broken off. That is the main reason I am getting a new switch. Like I say, once it is in I will try to find the other problem. Thanks again, Pete.
