I made up some square steel tube and strap brackets between the two bolts for the sissy bar/rack and the passenger foot rests. Tucked in behind and inboard of the shocks. Used the two holes in the side and two in the bottom of the bags with the supplied grommets. Maybe a bit of an overkill but they don't flop at all.
I had to remove the stock turn signals and use the lights on the bags for turn and brake after replacing them with high bright LEDs. The lights that came in the bags are only bright enough for running lights.
