I don't have a part number but just tell them its for a rocket III. I paid $45 for the bracket. The License plate frame is a cheapie bought off ebay. It looks nice, but there are nicer (and more expensive) ones at some Harley stores I've been too. Once you get the bracket you can either reinstall your stock signals on it or do the frame thing. The mounting ears for the signals are pulled way in toward the center compared to the factory part. Either way it looks alot better without the factory part hanging all over the rear tire. If you go with eliminating your factory signals and replace them with aftermarket lights you will need to get the resistor pack to make them flash slower. A good set of turn signal mirrors will usually come with one included so you might want to do that 1st. Use shrink tubing where you can, everything is exposed to the elements and good luck.
