Default NEED HELP lower control arm bolt

I'm trying to replace the lower control arms, and the rear bolt captured nut broke loose. I was able to drill a hole to access it, but how do I hold it to get the bolt out? is it a hex nut, if so what size? Vice grips?
Any help would be greatly appreciated, the bolt is stuck half way out.
Thanks

just a friendly note.. if you cut the floor with an angle grinder, take great care to shield the sparks from hitting the upholstry. the sparks will burn any thing with a felt feel, such as a seat, headliner, or visor almost instantly.

Might try getting someone with a mig welder to tac the flat nut so it doesn't spin anymore.
Then try screwing it back in and put never seize on the threads.

The nut has 2 flats instead of 6 on a hex nut. It's almost an inch wide. In addition to the other comments, I'd suggest stuffing a rag into the frame below the nut (from the top side) to catch your tools that will try to fall down there.
The first trick is to stuff an allen wrench between the nut and the cage, then try to tighten the bolt. This might clear any rust that was caught in the threads. Add WD-40 etc. and work the bolt back and forth until the oil gets in there.
If you haven't already done the other side you may want to drill a small hole in the floor to get the WD-40 straw in there to soak the bolt on that side ahead of time.

Success! The allen wrench trick worked like a charm. I tried using a screwdriver to keep the nut from spinning, but no joy. The allen wrench worked out and in. I was able to screw it back in a bit, clean it with a small wire brush(after a trip to Lowes to get one), more PB, and was then able to back it out. Getting the arms out and in was a pain!
Walazono, if your ever in NJ, give me a shout, I owe you a burger and some beer!

Thanks!!
