Installed mine used no, instructions only one screwup minor.did mounted control on wrong side.......did not seam quite rite, checked on line now its correct..
What are the part numbers for the adjustable back rest you installed on you bike? I would like to do that, but best I can tell from the HD website, is the backrest pad is about $100, and the frame and mechanism is another $200. Is that your experience?
