Hi there. I was trying to remove my dash to repair a broken trip reset knob, and I hit a snag. It seems the threaded studs, where my speedo and tach cables attach to the back of the dash, are loose. So, when I try to loosen either cable, the stud just spins. Hence the cables are stuck (for now). Has anyone encountered this before? Any suggestions to hold those studs so I can unscrew the tach and speedo cables? Thanks!
