Steering Wheel/Horn Button Issue & Ques?

[blink32]

Ok, so its a 76 Chevy K10. Horn didn't work when I got it off my grandpa. And after some investigation I think i'm missing a part or its put together incorretly.

The button didn't have any kind of "spring" or pressure to it, it just fult like it was pushed all the way in all the time. So I ordered up #8, horn button kit with the spring, rod and retainer:



Open up the steering will, and discover that I have the spring, but the rod and retainer are missing. Install the new spring, rod and retainer in the RED circled hole:



Now if I touch metal to the top of that rod then to the steering colum or the steering wheel mount the circuit grounds and the horn sounds, so I know the rest of the circuit is good.

Here are all the parts that came off of it, the steering wheel nut retaining clip is hard to see so its circled in red.(i only took the nut and reting clip off because I thought I was going to remove the wheel, but I had no puller):



And here are all of the componets installed in the wheel:



That large thin metal washer type part goes on first and it is totally smooth on both sides, then the cup with the 3 screws on top of it. I still have no horn, although the button seems to have tension now and I can push it down and it feels like a normal horn. But I don't see any way that the rod that is recessed in that hole will ever make contact with anything metal to complete the circuit. There is nothing protruduing down into the hole from that spacer. Am I missing a part? Or am I putting it together incorrectly? The rod that is in the turn signal cam is installed as show, flat end at the bottom, spring, then retainer on top. The only thing I can think of is if there maybe is supposed to be a spring below it as well to push it out just a bit, then as you push down on the button it will in turn push down on that thin metal spacer making contact with the rod? Any help is appreciated.
