As you are so good at answering my obscure little questions, here's another one.
The horn button on our 1966 Mustang
won't stay on the steering wheel. No matter what I try I can't get it to clip on and stay there.
The button is a metal die casting which just seems to be a push fit onto a plastic ring which is mounted on three bolts and springs and has the horn wires connected. There are three small nicks in the edge of the plastic ring but no matching bits inside the horn button. Not matter what I have tried (short of using blu-tack) it won't stay there and just pops off again.
Is there some art to this, or am I missing some special clip, or what?
