My recently acquired 04 RC51 came with a cheap undertail installed, and am looking for a complete stock undertail with tail-light assembly and associated hardware. Let me know what you have, and pictures always help. Thanks!
Original unmodified undertails are hard to find - you may want to check into the price of a new one at partzilla.com
Tail light assemblies are easy to get. I have one you can have for $50 + Shipping if you can't find one closer to home. I'd check on Ebay first though...
