Looks to me like a cable pull. I'd think you need to disconnect the far end of the cable, and remove the nut or clip that is holding the bezel to the dash and remove the entire cable assembly. If you can straighten the rod enough to reuse the cable, the best way to remove the knob is probably to clamp the rod in a vise, protected by wood or cardboard, and place a crescent wrench against the bottom of the knob and give it a couple of hits with a plastic hammer. All of the dash knobs on my truck as attached with JB Weld.
