1968 Barracuda 383 Big Block torque boxes ?????

This for 68 only. On 68 Barracuda all the 383 fastback cars I have seen or owned all had torque boxes. Autos rear only and 4 speed front and rear. I did have a 68 Barracuda 340 4 speed notchback had no torque boxes front or rear.

I believe 67 68 69 Barracudas some can with torque boxes and some did not. I do see more missing on 69 cars and more on notchback cars
