I've also got an aftermarket hub (D1 spec i think) with a Nardi Deep corn steeringwheel on my MC2. I was just wondering how you guys have run the horn grounding. I've used some steel wiring and had to bend it with a curve to contact the back of the hub(brass part) and the ground on the collum. How did you guys did this, I'm just curious.
I'll show some pictures later so you guys have got an idea how I've run mine.
