I have the MoCo edge cut boards and highway peg and eventually the control levers on my FLHTK. I haven't been able to find an air cleaner cover to match. So I purchased the flat cover with ball milled grooves from Jamie @ Fuel Moto and had it powder coated black($10). Then had the machine shop guys mill it out to match the edge cut collection(12er of Guinness). All I have to say is I LOVE IT.
Looks great! I've got something similar on my bike, and was thinking of getting it powder coated as well. (not the FM one, this one is an ebay find, originally intended for a VW Zenith carburetor, I think)
