Horn not shutting off

['68OrangeSunshine]

I have an issue currently with the Horn Button making contact at the wrong time or all times. '68 C/10 Stepside. Manual column. Three Spoke Wheel.
I first disconnected the Horn from the Horn Relay, but the constant clicking drove me nuts, so I pulled the plug from the Relay too.
I think the problem stems from an old upper bearing pack in the steering column. It's missing at least one ball bearing, maybe more.
[Truck is showing ~ 406,000 on the odometer.]
Also the screw holding the Turn Signal Lever to the T/S Switch fell out, and the Lever is loose on the dash.
To make turn signals, I use my Hand Signals. At night, I wear an orange safety glove with white reflective taping on it.
When I'm done refinishing my OEM Wheel in Fawn paint, I will try a new Upper Bearing Pack and re-attach the T/S lever.
If it still honks when not wanted, I'll try the Lower Bearing Pack, but that requires pulling the whole column out.
