How did you manage to fit it in there, my plate is too big to fit in that gap. Also, where is it screwed into, it looks like the screws are on the edges whereas the only place I canthink to screw it is in the middle.
I'm looking at making a holder to fit in the tow hook, inspired by this: http://www.stillen.com/product.asp?id=STILICBKT01&c=EX&r=&b=&m=all
