I'm trying to restore the previous rear tail-tidy to stock and would like to buy the pieces that the tail-tidy removed.

I think it's the following parts at this website (which is pretty awesome in how it deconstructs our bikes).

Part 3: 63113-04K00 - Fender,rear rear
Part 4: 63116-04K00 - Shield,rr fender

Note there's two rear fenders. I want the one that holds the license plate and blinkers.
