1964-65 Barracuda question
I agree that you're more likely to find an S car than a heavily optioned non-S car.
There's other things to look for to verify Formula S or not -->

A factory sway bar will look like this attached photo where it's connected to the K-frame.
3 1/2 turn fast ratio steering (16:1) was an option, not a Formula S feature. 8 3/4 rear was optional, so it could be the original rear, but who cares? An 8 3/4 rear is more desireable anyhow.
If it's not rusted out, grab that Fish man!
