Will the BRONCO BILLET TIRE TREAD DASH KNOB & BEZEL MASTER KIT work on the 1966? Or is there a specific kit for a 66? Thanks, Scott

This kit is not available for the 66, only for the 68-77. This would be the closest kit available for the 66-67. You may start with the #6403, and fill in where you can, with individual pieces.
