Do we have any torque box experts on the board. I know that torque boxes were installed on certain A bodies, GTS 340/383 etc. Were they installed front and rear?
All A-Body cars with the 383.
All A-Body cars with the 340 4-Speed.
All A-Body cars with the V-8 and convertible.
1969 440 Cuda and Dart GTS 440.
But that is not 100% completly true, as some other combinations
were found to have Torque-Boxes, and several 340 cars were not equipped with the frame unt.
