The Easy Bracket Saddlebag Bolt-on Support Systems allows you to make your saddlebags quick detachable to attach securely to your 1996-2005 Harley Davidson Dyna with a detachable backrest. The center to center hole measurement is 10 3/8". If you don't have a detachable backrest or want to use the center to center holes that are 9 5/16" see the DNA-R1. The Easy Bracket kits include both left and right side brackets with four (4) stainless steel docking points to mount to the motorcycle fender rail, and all necessary hardware to mount the brackets to your saddlebags with only basic tools. Turn signal relocation is necessary on all Dynas and Wide Angle Saddlebags must be used with this bracket.
