69 383 barracuda

Hey guys new to the forum and would appreciate the help. I am about to purchase a 69 barrasuda 383. My questions start with is it a formula s or cuda. i thought you couldnt have both on the same car but this car has both emblems. the vin verifies it as a 383 car but the fender tag is gone. The build sheet is partway there with the vin on it, the drivetrain is numbers matching. How do I tell which package this car has without the fender tag. the car is a 4 speed, has the hood scoops, disk brakes, 383 s emblem on fron fender, and cuda 383 sticker on back fender. Any info would be greatly appreciated,
