I'm finally getting to repair the rear fibreglass bumper.  Both corners had been damaged by a PO.  I need to remove the bumper by removing the bumper brackets that are held to the frame by 2 bolts each side.
The problem is that one of the nuts that are welded to the inside frame member is loose.  When I turn the bolt the nut turns also.  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.
Any suggestions are welcome.
