Another option may be if we can find someone with a very good original. I know a plastic injection guy who makes very good replica 900/750 panels. He is trying to replicate our RC/RD toolbox, so far his work would be difficult to tell from original except he can not reproduce the hinge. Since the rear mudguard is a simple panel I don’t think he would have any problems. You would still need to find the registration plate bracket but it would be considerably cheaper than getting one from the USA.
