Damn, man, that does look nice. Color me envious.

My previous bike was a Road Glide, and I miss the fairing. Not a matter of deciding if I like the looks or performance, just trying to identify technical hurdles. As for trading in, don't think I haven't thunk it. But, none of the 09-current CVO Sharks really ring my chimes. Fell in lust with the Road King the moment i saw it. I just want some more wind protection for the long-hauls, and I'd like it to look good, too.
From what I've gathered, if it was a non-stereo'ed Road King, this would be relatively easy (not cheap, but relatively easy). It'd just be a matter of getting the parts and harness for an equivalent-year SG/Ultra.
Difficulty is figuring out if it's possible to use the existing speakers and integrate them with an H-K head unit, and if so, how. Or rather, if it can be done before the money burn speed hits 'ludicrous'.
In touch with Glenn at Woodys Fairings and Joe at Xtreme Dimension for the paint, may go that route. At least I know that can be done, how much it'll cost, and I can do it myself in my garage! Just hope it doesn't wind up looking like a goofy hat on a racehorse, you know?
