Locking Petrol Cap AU Ute.

Anyone know if you can get an petrol door locking unit, plus remote release for AU Utes?

I hate the fact that its not lockable, sure I could put a different internal lock cap on, (and will do so if above is not possible) but would like to know if anybody can suggest if this can be done, or if another model would fit, and do the job.

even just a petrol door with a lock on it would be ok. Be cool to have an automatic one though

Bloody petrol theives!!! I should P1ss in it, that will teach you.
