Sorry Ken! I was going back through some notes and for some reason thought it was Alex.
On the older style GM column (like the one shipping with the kits now), the horn doesn't use a clock spring, but a contact disc with a plunger that sticks through a plastic housing. They used a separate clock spring for the airbag connection.
Unfortunately I didn't take pics of the plunger setup, though.
I'm pretty sure it's still a GM rack, but I'm not sure what year/model it's from (i never bothered asking Fran). GM and Chrysler used the same steering wheel hub design for many years.
Knowing which make and model would be really helpful. I just found the tilt feature on mine LOL.
Would like to make a pull for it or get one from a junkyard.
