FLT King Tour Pak Luggage Box Lid Locking Hook, 1981-83 (OEM #53306-80)
Factory references show first use in 1980, and we are finding it as late as 1983. There was also an early number, OEM #53306-69, but a change in part number indicates some change in design, so we can only confirm use for the 1981-'83 model years.
