65 Dart Horn Problems

@eekvonzipper - To me it appears you're copper ring was installed upside down. The raised area around the center (as pictured) should be against the backside of the steering wheel and not facing the turn signal switch mechanism. Easy to see why you had an interference/touching problem. After seeing yours, your right, he may have the same issue.
There is no Raised Center. It's completely flat and only copper on one side, it's all phenolic on the other side.
