Caged Nut on FrameRail Repair
What a pain, There was a jerk that cross threaded one of my main subframe bolts. I tried to repair with HeliCoil, but after two months I've noticed that it wasn't really holding. I cut a window and next week I'll be getting together with a friend to weld over the window. If I can figure out the best way to get this "caged nut" out I'll be ok. Looking at how this nut is in there I just don't know, it's going to be interesting.

Yesterday was all about helping others, no work on the nut, but Got it Figured out...
I helped two other forum members yesterday and had no time for my car, but at the end of the day the second guy that I was helping looked at it and came up with a great idea. Rather than butchering the inside trying to get the caged nut out, I will instead keep the caged nut thus retaining the ability for the nut to move and saving my knuckles a lot of blood. I'll drill through it, then run my new bolt through the caged nut to the new nut that will sit on top of the caged nut. I'll weld the new nut to the old nut and SWEET!
On an alternate note, of interest I had my old dogbone and poly laying around, the second guy that I helped yesterday jacked his car up to swap mine in and found that someone had done significant damage to his dogbone and subframe. I was really surprised it still worked. Pretty massive speed bump damage. Chisel/Mallet/etc and we got him all hooked up.
