I have recently acquired a 1985 R80 mono shock with what I assume is a dealer option RS setup (fairing, bars, bags etc) and can't seem to locate one of the keys for the pannier bags.  It is coded "040" on all three of the latching mechanisms for that bag, but the keys are apparently made of unobtainium!  If anyone has an extra, or knows of where I could get such a thing, I would be appropriately grateful!
