Anyone know if you have to use a mounting bracket with throw over bags for a 2001 sft.d. The rear fender hangers appear to not have accessable bolts to attach hangers to. Would you have to drill through them and then bolt brackets to them? Even though they would sit on top of the fender under the rider seat I would not like to have them flopping around and get hung up in the wheel. That probably wouldn't be good huh, lol Tks. for your insights.
