I have tried to get an answer on this but no one seems to know. The dealer say's bring it in and for a small fee $$$ we will try it out. I have been trying to get my wife more comfortable on her 2015 Freewheeler. I put the Mustang seat on it which moves her forward some. But when she is sitting comfortable on the bike her heels are hanging off the back of the boards so what I was thinking after looking at them is HD makes the boards/mounts that move the boards forward 1" and as far as I can tell they should be able to be swapped around to do the opposite and give an inch back which would work perfect. Anyone !
