I have a stock rear fender and license plate bracket I'd sell. I'm using my stock 919 turnsignals but I have at least one rear t/s assembly off our 599, might have two. Different part number but physically identical to the 919 turnsignals. They're a bit scratched up but useable, also have several stock amber t/s lenses. Will have to dig through some boxes and see exactly what's there, could take pics of the turnsignals so you can see their condition if you're interested.
I just pulled my rear tail signals and mounting completly of in one peice. only thing that would be missing is the two brackets that hold the side reflectors and a couple bolts. I used those brackets and a couplt of the bolts to fashion a plate holder.
