Thanks for the help. Yes, I did all that. I can basically stick a screwdriver on the contacts at the horn and it will blast away, then I used a wire to trace all the way. I got a new under dash harness and a new turn signal harness. New horn relay. Electric is live all the way through those and when I run a test wire from the upper steering bushing, which is new, that is active. When I put together the steering wheel and horn contact spring and the metal cup it will beep intermittently. All of the brass on the steering wheel is clean. The only other thing I can think of is if somehow the steering wheel itself or the brass on it is warped slightly which I can't detect with just my eyes. It's a mystery. Sometimes when I push the horn cap it will beep and then nothing. Horn cap is good, rubber is good, plastic 3 screw ring is good. Then sometimes I turn the steering wheel slightly and it will beep and then nothing again. I'm ordering another horn contact spring on the odd chance that the new one I got is faulty but they are pretty simple so I don't know what could be wrong with it. Anyway, again, thanks for the suggestions. If I do figure it out I'll post my remedy in case anyone else runs into this. Still open to more suggestions.
