I just went through this problem on my deluxe. I have Vance and Hines short shots and it was the same problem. I was pretty frustrated with my options one of which was to make a bracket from the stock muffler support bracket which is how the floor board is supposed to mount but I came up with something WAY easier albeit a bit more expensive. I stared at it for a while and saw it. You can use the same set up that is on the left side on the right and it works out perfect. I ordered up a duplicate set of part #s 50464-07, 50465-07, 3601 and for $80 more I was set. Not thrilled that I had spend an additional $80 but it worked perfectly....with a slight modification and here that is.......the mount (50464-07) had to be shaved slightly where the "U" portion sits on the swing arm pivot. I just used my compressor with a grinding wheel. Nobody can see that the powder coating is gone because how it sits. Took a few minutes to put on after the parts came in. Hope that helps. Can post pics if it'd be helpful.
