Set a "Followed Search" on Ebay and things will eventually show up. And then, if you are diligent at looking at Ebay for the announcements of these searched "finds", the parts will be yours. But don't go nutty as I've done getting into a bidding war for an ST90 luggage rack. Fortunately, I caught myself and stopped bidding somewhere around $215 or so headed north of that. Insane.
