They were standard on Hemi cars and ragtops, right? Any other cars? I was reading about the Charger from the TV show "Chop Cut Rebuild" and the pedigree of the car was under scrutiny. The Hemi was not available on an XP Charger but this car is coded for it, and it has the torque boxes to lend credence to it being a real Hemi car. I assume there are examples where the car was built with torque boxes but wasn't a Hemi or ragtop, right?
