Question about 1969 Barracuda

I recently bought two barracudas. One 1968 and one 1969. The 69 was a 383 4 spd car, I believe a formula s. It still has the 8 3/4 rear under it. I'm relatively new to the Mopar world. What options for gear ratios would a 69 383 formula S have come with?
Thanks,
Colton
Not sure if the 3:23 SG was an option because I think Ma MoPar threw in some 3:23 peg legs under these cars, but 3:55 SG and 3:91 SG were options.
