Custom wheel horn install

[ol Curt]

Any of you have a custom wheel? I have one from a Nova that I feel should work. I was missing a plastic spacer and got one of those from Tony. I can put the piece of spring steel on and depress it and the relay clicks (horn disconnected)....but when I try to put it all together it doesn't have any spring to it. I'm putting the spring steel piece in with the convex side up (toward driver). Everything else looks right, but if I screw it down firm it doesn't work. If I leave the screws slightly loose it will work, but doesn't feel like it should be that loose! I have it together just like this guy show in his pics below. Is it possible the horn button piece could be bad. I cleaned the contacts up in it, but wonder about the strength of the spring in it.
