Cuda on the bay misrepresented

I see this is kind of an older thread but just for the heck of it took a look at my 66 Barracuda brochure just to see what is says about a Formula S. Basically it says the Formula S package includes the Commando 273, rallye suspension and heavy duty shocks, wide rim (14 x 5 & 1/2 in ) wheels and special Blue Streak tires, tachometer, and the wheel covers that simulate bolt-on wheels. Says nothing about a 150MPH speedo. I was under the impression it was standard on the Formula S but guess it could have been optional. Does mention optional equipment as the new console for auto or 4 speed, and disc brakes as well as other optional equipment available on a regular Barracuda was also available on the Formula S-equipped model.
