FUBAR'D Hex Hub?

[jpoprock]

I'm experiencing something that is about to make me flip out. I have some 23mm rims mounted on my Losi, and I can't get the hex nut off. The problem is, when I try to loosen the nut, the hub is turning inside the rim hex and I can't get a good bite on it with some needle nosed vice grips to hold it in place. The hub assembly is in the way! I'm afriad this awesome Commanche rims of mine may have to be broken up and ruined now. I can't cut the hub off, nor is there any other way of getting that wheel off. I have never had this happen before, and I am NOT happy! Any suggestions?
