How to ground Spit steering column so horn works ?

[jw@mail09.mitre.org (Joe Whalley)]

My horn switch does not work, and I find that the inner steering column is not
grounded, so the horn switch does not provide a ground path for the relay. How
is this inner column, which seems to be isolated with rubber bushings,
supposed to provide the path? There must be a better way than just clamping a
wire to it, which would eventually break from turning.

Thanks - Joe
