Second Generation Barracuda Year to Year Differences

Did 67 & 68 Formula S Barracuda's come with frame torque boxes? Obviously the '69's did because my A56 has all 4.
My 69 383-S had no torque boxes and a bench seat. I spoke with another 69 383-s owner that had a bench seat and his did not have torque boxes. The use of torque boxes is all over the map. Some had four, some two, and some none.
