FWIW FP I did find the ones on EBay motors from Thailand, and there's measuring instructions, either 9" or 11", so I really have to get down there and see what these look like. My bet is that they'll fit but still not sure about the amount of room between the caliper and the wheel on the NA, may have to shave the back of the cover. It's only ABS so a dremel sand would be easy, but I do like the smooth look of the covers. I'll be sure to let you know what I find out. Hope others can chime in here too. I saw the threads before, albeit sparse, so not alot of info.
