After seeing drivers back rests on here I made my own. Took off driver seat and saw how passenger seat is bolted. Removed that bolt and saw the bracket, that's mounted to the fender, had a slot. Bought small length of steel from home depot (under $10). Cut it to length. slotted both ends, bent into L shape and slid one end through passenger seat bracket then dropped bolt back down and tightened. To the other end I mounted a matching yami
sissy bar pad I found on e-bay for under $50 bucks. Best accessary yet. Don't know how I took those long trips without it. One dis-advantage is, it is not a quick release / remove type setup. So consider that.
