Help... How to remove MS3 strut tower braces?

[Unoriginaluser]

Can't figure out how to get the last bolt off underneath, any ideas? I took some pictures of the brace and the bolt in question. I can see the nut below but not the head itself. Not sure how to get the brace off

I looked at mine and it looks as if you are going to have to remove the plastic cowl above it (right beneath the windshield).
