i dont suppose anyone has a spare/unused one of these anywhere?

It would help if you include what sort of car it's to fit- there are so many different sizes and shapes of guard.

:) oh! its a fiat punto, the small kind!

remember if you're using a dog guard that your boot will spring open if you're shunted in traffic, so it's best to tether your dog in the boot too

ah I did not know this thank you forletting me know!
