Hey Everyone. We bought a Ford Factory locking gas cap for $50 for my dads 1999 Ford Expedition after someone stole gas out my moms car. We put them on all the cars. Well he only used the gas cap for a month and bought an 06 Ford Expedition. We tried to put the locking cap on his new one but it does not fit.

What years would this gas caps fit for and what other cars would it fit?? Anyone know. Anyone looking for a locking gas cap let me know. Like brand new.

Not trying to be a sales man here, just wish it fit or trying find out what other cars it would work on.
