I don't have the -14 plans but I checked the -6 plans (and the -10 even though it has different mounts) and the exact callout was AN-960-716 washer under nut as required. I admit the wording is a bit ambiguous but at least one washer is required; you may need another, thick or thin, to get the cotter pin in at torque.
