Removing Bumper

[2052006 10]

Trying to remove the bumper today in the freezing cold (not such a good idea), but got stuck when it came to removing the side nuts/bolts. Got the two 13mm ones off at the front, but there seem to be 2 nuts each side of the bumper.

 

They are rusted to buggery, so can't tell exacty what's what and how it's meant to be removed at the sides. There seems to be 1 x nut in the wing, going through a small "beam" and 1 x nut which is recessed slightly, further towards the front of the car. Do both have to come out or what?

 

Thanks
