69 barracuda 340-s VS Formula-S

More confusion,,,,,

If you ordered the basic 1969 Plympouth Barracuda with the Code #E55 340 engine
package and required Code #S13 suspension package, the car came through with a
'Barracuda 340-S' emblem on the front fender.

Now, if you opted for the upper-body horizontal 340 Stripe Kit option, the '340-S' was not installed,
and the fender than came through with only the 'Barracuda' emblem.
