Hi, I have a Momo hub with the dual contact ring to install on my 280SL. The dual contact ring is a loose piece and lines up with the factory dual contacts on the steering column. The Momo hub also has dual sliding contacts, which i assume must be removed to install the loose contact ring, since teh contact ring is one sided. I don't see anything to fix the contact ring to the Momo hub. It looks to me as though the contact ring needs to be attached to the hub somehow, so it will rotate with the wheel and not pull on the wires, but I don't see any method to attach it. Does anyone have experience installing these Momo hubs on this dual contact Mercedes horn setup? The factory box did not contain instructions and it is not like any other Momo hub I have installed before. Any help is appreciated.
