Bull bar install/ black out need help

So I bought a used bull bar for 100 it mint condition. I understand how the mounts work it's self explanatory however I'm have an issue getting these damn factory nuts off. I didn't have a good socket set at home I got one at work but went and picked up a good set and still nothing out of these nuts, already cut the back of my hand when she slipped. Anyone have an issue with these nuts? Any tricks for getting them off?

 

If its the same bumper nuts that I removed for my Avid bar, I had to use a socket wrench, lay down on my side and put my foot on the handle and leg-press them off slowly. Be careful or you could kick a hole in your bumper cover if your foot slips off.

 

Ye that's I had to get a long socket wrench but that did its in and good to go!
