Can't drop the frame with that bolt in. That's the catch. Is your car manual or automatic? On my manual 05 cobalt I removed the rear mount and cut a little piece of metal where the nut is so that I could bend it down enough I slid what I remember correctly was a 1" wrench in. May have been 1 1/16" wrench. The nut isn't really a nut that you're thinking, it's actually a piece of 1/4" steel drilled and threaded and rectangular in shape. After this I put the air gun to it and zipped the nut off. Normally this happens when the bolt is seized into the sleeve of the control arm bushing so when you zip the bolts back in coat the bolt in grease to prevent this next time (not the threads). I have heard people cutting their drivers floors out but I'm not into that.
