Hey Philip,
Yes, the '68-styled cars in the '68 commercial were actually 1967 models in disguise. it is likely this commercial was filmed circa July 1967.
We haven't identified the red Ford Mustang's VIN. It could be one of three regular '67 Mustangs that were in SAI's company car inventory, along with eight coupes and three convertibles. Or it could have been sent to SAI's Show Car division by Ford for prep and photography.
The Acapulco Blue Shelby G.T. 500 fastback is '67 #0463.
Prior to becoming one of
two '68 photographic (advertising) cars, #0463 was specially requisitioned to serve as the official "AC Cooling Test Car." Pictures exist of #0463 at the Goodyear high-speed test track in Texas along with the
427-powered #0544 (nicknamed the 'Super Snake'). At this time, #0463 was still Lime Gold, though it had been fitted with the '67-1/2 style front end (outboard high-beams), louvered hood and oil cooler for the official testing. The
G.T. 500 Air Conditioning topic is mandatory reading on this topic.
Both cars appearing in the '68 TV commercial, the Red Mustang, and the Acapulco Blue Shelby GT500 were on-hand at Ford's annual Long Lead Technical (LLTC) conference, which was held July 6-7th, 1967 at Riverside International Raceway. The Press day was the 7th. After the LLTC event, on July 10th, the advertising cars, including two Shelbys,
#0139 the G.T. 500 Convertible, and #0463 the Acapulco Blue fastback, along with three Ford Mustangs,
a white convertible, turquoise coupe and red fastback, were all taken to Idyllwild and photographed at several scenic locations. Other Ford products may have also been taken to there and photographed, though we haven't performed any research on them.
