Horn Button - 68 SWB

[jwbchevy502]

Just installed an ididit tilt wheel, steering wheel hub, and steering wheel all from CPP. Everythign went extremely well and fit like a glove like almost evrything I have gotten from those guys. My issue is the horn button. Two problems - one, the horn button will not stay in the wheel (There is an o-ring but no fastner, clip or retainer to hold it in place), the second issue is the horn itself. Checked the relay it works fine when I jump it. I have 12V to the relay and no apparent open circuit to the ground and horn side of the relay as well. Any ideas out there I should would appreciate it. I'm 99% complete with my build and would like to wrap this interior up. Any help would be greatly appreciated on both issues.
