Best way to get stripped nut off.

I'll stuff this in the category of "Interesting". Just a few questions so we can figure out where you're at. How long is this thing you're calling a torsion bar? What size nut would you say it is? Where is it located? Do you have a camera so you can post a picture for us. We're tryin to help. Dont sound like you're dealin with a torsion bar to me. Dont be embarassed. We were all in your shoes at least one time in our lives. Tell us what ya got and where it is.
