Is the problem that the bolt turns but does not undo because the captive nut in the rubber part is rotating i.e. not captive, you can feel the nut rotating if you can reach the rubber nut holder...
It may be possible to clamp the non captive nut by squeezing the rubber around the nut with pliers, or was that what you did. and then unscrewing the bolt, hopefully.
Can you take the front panel off with the screen still on it, cannot remember as my TA is naked, then you have better access to the screen nuts or are the side panel/front panel nuts stuck as well.The bottom front panel/mounting bracket bolts have 'captive' nuts embedded in the front panel these stick as well. If the are rotating you can pull the front panel off the bracket and unscrew the 'captive' off the bolt and glue in back into the front panel. I replace the bolt with a stud glued into the fairing then it is easier to fit the fairing onto the bracket holes then fit a nut onto the stud..
