I'm still in the middle of installation, wiring up my 3CS with the rocker switch & powerlet socket. Here's my top/bottom clamps and bars I got from Paul. If you plan to do a rocker switch make sure you contact Paul or make sure there's an option for the rocker switch as it needs more machine work done for the rocker switch than the powerlet..
The quality is very good and Paul @ HDB was a pleasure to work with on this project, I'd highly recommend them. Now I wish I had their handguards too :)
