Set of 3 Black Anodized with Knurled edge HVAC knobs for 2004-2006 Pontiac GTOs.  These are not covers and it is required to remove the HVAC control unit to replace which takes about 1.5 hrs at the most.  Detailed instructions will be included.  If you have the OEM radio, the radio needs to be removed as well which requires the radio removal tool (not included).
