I just tried to remove my rear body mount bolts on my 69 Chevelle - they were coming nice and easy because I worked them back and forth however the dreaded happened - the built in nuts started to spin. Should I cut out a slot at the rear of the panel to try and get a wrench on this, or any suggestions. This is a real nice original SS and I don't want to butcher it up

Thanks

Ed... This happined with my 71. I drilled a 2 in. hole with a hole saw and my right angle drill. Then I held the nut with a wrench and removed the bolt. Then you can weld the circle back that you removed. Grind it, a little plastic, paint and your set.
