Removing bull bar

Hi there, I am having trouble removing the bull bar in the pictures.

I can see 2 nuts just above the nuts for the front bumper (on the inside of the bumper where you remove the nuts for the plastic trim) but one of these nuts won't budge.

It isn't rusted on, and it isn't rounded. Yet when I loosen it the ratchet will un-tighten it and keep doing so, but the other end of the nut keeps spinning in place, but I cannot reach it due to the bull bar being in the way???

Any help is appreciated

remove the entire bumper ? I think its bolted in from behind into the metal

No not the entire bumper, I just want to remove the bull bar part of it as I don't like the look!

Anyone know how it's fitted? It seems to be attached to he bumper somehow...

Dr evil has just told you how to remove it.

Take he bumper off.cut the bolts with grinder and remove them then spit bull bar and bumper and refit bumper with new bolts
