torque box pics???

The REAR torque boxes are typically found on '63-'69 A body convertibles and most stick application V-8 cars above 273 cubes.
You do know that there are FRONT torque boxes on A bodies, as well?
They seem to come about in '67, but I've seen them most in '69-'72 stick performance cars and convertibles.

Even some 318 3 speed cars have them.

I all truth, with a good set of sub-connectors and a cage, they are totally unneccessary, therefore not worth making and welding in.

Mark.
