I do alot of escourt rides for our local vets I made a two flag holder by removing my passenger back rest and sissy bar. Then took some 1 in. ss key stock cut it 5 in. long and milled dowm two inchs from the end 1/2 thick and drilled it to match the holes in braket that holes the sissy bar then cut a 3x1/2 inch ss flat bar an inch wider than the outside of the braket and slotted it 1/2 in from each end 7/16 wide 1 inch long then drilled the key stock for 3/8th bolt to attach the 3 in flat bar. I then drilled to holes in the flat bar so two 1 inch sch 40 pipes could be welded top and bottom. The id of the pipe will accept 3/4 thin walled metal conduit for the flag poles ,the ss polishes out real pretty with some work I used 1 1/2 clevis pins to hold the polls to the braket and to keep the flags from turning in the braket you will need to lock tite all 6 bolts to keep them from coming loose the braket is very secure to the frame,just tighten the bottom four bolts then the two top bolts. I used 3/8th inch ss fender washer to cover the slots just make it look better
