I wouldn't take the video as definitive. While the gauges are wrapped with walnut, you'll also notice in some of the other videos (this one in particular: http://www.gettyimages.ch/detail/video/pontiac-firebird-styling-stock-videomaterial/450000638 ) that other styling features unique to Firebirds or certain trim packages are present when they shouldn't be.

Yours appear to be black in the photo, so unless someone removed the walnut, I would say you have a Camaro set of gauges. We also know that the Camaro dash center piece came in the pebble grain black, matching your gauges.

If the video were filmed before the release date when all options were finalized, that would explain their appearance(after the 8 track) in the sample car and not in the final release versions.

In support of that I would note that the driver in the series of videos, Pedro Rodriguez, while he did in fact drive some races for Ferrari, they were in the 1966 season. By the 1967 season he had a full time ride with Cooper and in fact on January 2nd of 1967, he won the South African Grand Prix while driving for them. The Firebird was released on February 23, 1967. Now, because Cooper wouldn't have been a well known name in American households, the use of Ferrari, even though he wasn't driving for them at that point, would draw more recognition.

Thanks for linking to the video, however, I don't believe it proves that they were available as a factory option from Pontiac. Dealer installed perhaps, but again, wouldn't they match the walnut trim? Also, what isn't shown that would also go in that same location as the 8 track and those gauges is the clock. That isn't in any of the videos that I see.
