I bought a chunk of round stock and had a machinist buddy cut off a couple 1/4" disks and countersink holes to mount to the factory steering wheel and collar mounts. Works great and looks stock. I did cut the collar apart to shorten it 1/2" to move the wheel back to the stock distance. No horn at the moment but I'm planning to work that out this winter.

Fixed the orientation of the photos. Dumb iPhone.
