Grant horn button help!

Excellent job on the pics! You have went above and beyond to help out. After seeing that, it looks like what I'm missing is the contact piece under the horn button. Now if I can just figure out where to get it. I still don't understand how it will stay in place and yet keep the button from falling through.

If your billet ring is the same as mine, the horn pushes in from the outside and cannot fall in.
