Bryan, here are pics of the Tuff Wheel I mentioned having. Let me know if you're interested. It looks worse than it is; that white stuff is sanding/grinding dust and blows off easily with air.
Make me an offer on it via PM if you'd like. Wheel, cap, horn switch--they all go together. I don't have an adapter since I need the one on the car (it's too long anyhow). I'll clean it up and take more pictures if you'd like, too.
