What type of dart do I have?

Two barrel four speed A-bodies from the factory are rare, but they are out there. Also no cutout on '66 or '67 Darts for the big resonator tip.
In the summer of 68, I was looking for a car to drive to college. One of the cars I found was a 67 Barracuda fastback with a 273 2-barrel and 4 speed. I passed on it and bought my 65 Barracuda non-S with a Commando 273 and 4-speed (also rally suspension with front sway bar, but 13 inch wheels).

Twenty years later my wife and I looked at a 68 Barracuda coupe with a 318 (2-barrel of course) and 4-speed. I would have bought it if I had not already had my 67 slant six coupe (now 360). Friend of mine bought the 318 4-speed Barracuda and replaced the 4-speed with an automatic. (?!?!)
