To Rockwell, I've always notched the bottom of the switch and let the wires run under the bars. With Clubman's not much chouce. Sorry you put so much effort into it.
To Andy: I think "clubman" is just a generic noun describing that look of bar. Like Drag Bar, or Ape Hangers, or flat trackers. Tommaselli is just one manufacturer of clubman styled bars, and they have their own design. Which is more to the point, where did you get them? I prefer that design where the clipon portion goes past the "U" portion, rather than the mitered joint. But that makes them pricier too I think. I've searched for Tommasellu bars and can't find them.
