Front bumper removal

[nebilex]

Hi everyone, I started removing the bumper cover so that I can change the aux fan.. I was able to remove all the bolts without any issue except for 2 of them: http://www.xoutpost.com/articles/x5/...r-removal.html (bolt #4 and 5)The problem is, the bolt and nut are spinning together. Unfortunately, these two bolts mount onto the front crossmember which is basically a tube. There is no access to the nut to grab it so i'm stuck. Any suggestions?

Drilling it would be a last option but then what do I do when it's time to assemble it back? I won't be able to connect the nut in the back.
