I bought a set of fender skirts from from Gary Wollard about six years ago. I never installed them - and, of course, now that I'd like to, I cannot find them! How do you lose four or five large pieces of sheet metal wired together in a bundle? Don't ask.
But to get to the question - were fender skirts ever offered as an accessory by the factory? Or were they all custom-made? I've never seen them referenced in any factory literature, but on the other hand they seemed to have appeared on a fair number of machines.
