K member frame bolt hole repair

[J-440]

So my tubular K member decided to take a crap and when it did, one of my bolt hole mounts got bent. I drop the member and the hole is now cocked and concaved and the nutsert broke loose. Is there a tool like a slide hammer that will go into a 1” hole, secure itself on the wall and then I can beat it out? The frame is boxed and is a unibody and I only have access through the 1” hole. Any help is appreciated.
