My 67 came from the factory with about 27 options. It has an Auto, power Windows, power seat, power antennae, power trunk release, rear window defroster, belt line trim, and some others. One of these are the headrests mounted on the optional bench seat. I have never seen any 67 A Body with a bench and headrests. The Dallas Pontiac club has never seen them on a GTO. . They are kind of hokey looking compared to headrests on the bucket seats. They fold a little forward for the rear seat occupants to have more room when entering and exiting the car. Any one seen others?

 

Found an NOS set of covers in an old dealership. Yes very rare. Mine are dated 10-66 inside

 

RPO A82 was a $42.13 option for 1967. Pretty rare, especially on the RPO A65 Custom Sport bench seat with armrest. Your Pontiac club friends are clueless, as headrests were also available on Pontiacs for 1967.
