How do you remove the rocker molding on a 1972 Cutlass Supreme? Any advice will be helpful. Thanks

 

If I remember correctly, there were screws holding the ends in the wheel wells and you pull forward as there is round washer screwed to the rocker that you slide it down.
It's been over ten years so maybe some one will chime in to confirm.

 

If you mean the wide chrome strip, it's bolted/screwed by tabs under the rocker. Remove the fasteners then slide the strip up to clear the mounting brackets.
