Another "happened to me" story. My Vol has the bolts inside out mod on the fender struts. I also have the round sissybar and the corresponding brackets. When I took the brackets off my bike, I noticed that the inside of the bracket was worn down through the chrome, but worst yet, it had worn the chrome off my fender bracket. So please check that your sissybar brackets are not touching your chrome fender struts. I put a small band-aid, literally Band-aid, that keeps them from rubbing together anymore but cannot be seen.
