Unfortunately, Ford didn't keep detailed numbers on things like that, so there's really no way to know how many were offered with that exact combination. They only kept track of Bullitts, Mach 1's and Cobras for exact numbers by option and color. Other than that, they list all cars by color, regardless of whether they're GTs or V6's. Same with convertible options.
