Sorry, to add to that, you will need to remove part of the old horn assembly from the old wheel and screw it on to the new Momo. There will be a screw hole already pilot drilled for this. It will be very obvious how to do it.

I think 101 Projects has a write up on it. If not do a search of the Board and the Tech articles as I'm sure there are many threads on this common mod.

Post some before and after pics when your done.
