69 383 barracuda

What all do you have left of the buildsheet?
To answer your question somewhat the "S" designation was applied to 340 and 383 cars in '69. The 'Cuda package was a 4 speed trans, dual exhaust with chrome tips, a rallye suspension, the twin scoops, a blacked out grill and stripes with callout on the hood.
So possibly could have both badging, formula S 'Cuda.
Hope this helps, more will chyme in to help you.

Hmmm, I agree with most of that. Except I had a buddy who had a real Cuda package 69 fastback, with an automatic. It wasn't some clone either, he had it way back when, and only sold it about 15 years ago.
