On my Ladybug, the bolts that hold the CP to the cab go through the front of the cab and through the hinge on the inside. All 4 or 5 of them spin freely when I try to remove the nuts on the inside. Any suggestions to get these off without destroying the bolts? I know I can use my dremel to slice a groove in the bolt head which will turn it into a standard screw and hold in place with a screwdriver while removing the nuts. I want to try to preserve them since they are original and metric. Thanks for any ideas.
