New in Box, includes 2 keys

Ad said this would fit '99 and up Super Duty Fords (amongst other makes/models...see list in pics, though it clearly may not be that accurate???), but it doesn't fit my '99 Super Duty Ford...they must have changed to threaded caps some time after '99...maybe '05???

If you have a threaded fuel cap this should work for you....in the pics, my current fuel cap on my '99 SD has the black and NO threads (3 little knobs instead that lock into the fuel fill nozzle)

$15 FIRM...CASH or VENMO
