I have a set of Legends on my FXR, and am looking now for another set to put on a Dyna.
The only problem I had with them was that the peg was not long enough for my fat foot. I would have to wedge it between the edge of the peg and the brake and shifter arms. But it was an easy fix, just turned out a 1 1/8th inch spacer. They came off of a totaled softie. I had also made some mounting brackets for them to get them positioned exactly where I wanted them.
Spacers and brackets...
