The american ones have a plastic insert recess for the numberplate and lock to fit into - wondered if anyone had one kicking about?
i don't know what you mean but i could get it for you
looks like this:

the plastic section the plate sits in!
if you're not in a hurry i can get one for you, do you want a specific color? what ever i pay for it in the junkyard and what ever shipping costs you'll be paying the same...
no specific colour - just whatever you can get your hands on - you can't get them in the UK!
How much do you recon you can get me one for?
You'd have a hell of a time making that recess fit. The hatch is very different. I've worked on them side-by-side. BTW, the plate recess can be had for about $28 new.
