I've had a few 69-72B 440 auto cars with them. All my 69-72B 440 4-spd cars had them.
None of my 65-72B/E 383/400 4-spd had them.
Have seen a couple 318B's with the rears.




My brother and I each have '71 4-speed GTX's with the torque boxes and have seen automatic cars without them. My guess is that all 440/HEMI cars w/4-speeds and HEMI automatics had them.
