starting on my 383 barracuda

A53 with V78 is pretty common! formula ā€œSā€ stripe delete. Just gets the 383S fender badges. It does not imply A56 though.

what tail panel is there? Black with S badge or Argent with fish logo?
I will look at it and see, the 383 call out is on the fender half way down to the rocker.
I remember seeing a fish,the 383 is a decal, not an emblem.I am happy there are barracuda experts here,as I deal primarily in Darts.
I will post some pictures soon.The paint on the hood and bottom half are like the 69 GTX.
