Spinning studs on barracuda grill, any tricks?

If your talking inside track, Ive used 2 part epoxy using tooth picks to dab bothsides of stud on bottom of track.

Ok, let me be very specific. I'm trying to remove the grilles from the header panel. For those that don't know there's 3/8" nuts on BLIND STUDS. In other words the studs are not accessible.
