What’s the exact process to identify a real 66 Formula S Barracuda?

came across this thread researching Formula S Barracuda's

i recently purchased one here in the UK that has only been here for a few years.

The Blue one is the Formula S

the 'Gold' one i purchased from the US about 8 years ago.


The Blue car is a genuine S and has been featured in this forum before.

the Gold car is a Commando non S

the Blue car is auto and has manual drums and steering

the Gold car i a 4 speed and has power drums and power steering. no tacho in the Gold car.

but i have managed to purchase a Kelsey Hayes disc set up and an 8-3/4 with a sure-grip to go on the Gold car.

That second car is the same color that my old one was originally.
