I have a chrome locking fuel cap for sale. It is old style and came off a XA ute. I have also seen the same fuel caps on XW & XY utes. Very good condition with key. It is way better than the standard fuel caps sold at Autobarn.
$15. I can send interstate at buyers expense if needed.

I can also be emailed revcore30@hotmail.com if you require photos.
