Metal thing's in boot ??

In the boot on the inside of the slam panel there are 2 metal plates with hole's in ,what are they for ?

Ripping open bags of cat litter and allowing it to spill in the boot as far as I can see.:):):)
 
No they're luggage hooks Matt. The 'Genuine Ford' cargo net's hooks screw onto the inner-most rear light studs (after you've made a couple of small holes in the carpet for them). Check the pic in my garage.

.......and if you have a net but cant find the OEM hooks a couple of extra rear light securing plastic nuts screwed on in the manner described by Manos will do the job. ;)
