For the bags on the bike I put the fender kit on, they are the chrome hoop type that mount only to the fender. I put a 3/8" spacer between the fender and bag mount and it put the mount out enough to clear the belt guard.
With Shores bike he was thinking leave the mount where it is and make a simple adapter for where the bag mount mounts to the fender, but his bags are already lowered 3 inches. The fender will just be catching up with the bags.
He did a beautiful job altering his stock bag mounts.
