This hardware kit is not required if you are buying new bags. The mounting hardware is included for new bags. This kit is for if you bought used bags and they didn't give you mounting hardware, or if you plan to use one set of bags on multiple bikes. This kit is for mounting CB5400 Retro Series saddlebags for 2005 and earlier model Dynas. It will not work for mounting other bags, or for mounting bags onto a 2006 or later Dyna.
