There were a few 318 4-speed A bodies. Friend of mine bought a 318 4-speed 68 Barracuda coupe back in the late 80s. Then he took the 4-speed out and put in an automatic.
Price was only $800. Parking lot dings, but never wrecked and no rust. I would have bought it, but I already had a 67 Barracuda coupe, figured I didn't need two Barracuda coupes.
