Those captive nuts are not attached to the frame. They are attached to
the inside of the removable bumper mount. You can replace the bad mount
with one that has both captive nuts still intact.

Getting the bolt out could likely be done with a sawsall as long as the
bolt does not just spin when you try to cut the head off.

Is there a way to hold the nut, or do I have to drill or Dremel that bolt off?  The next question is how do I secure a nut securely on the inside of the frame?  I don't have access to a welder.
