The Dakota IC cross member is out of production, probably permanently. Industrial Chassis no longer produces them or has the patterns and jigs. So one of the best made alternatives has evaporated.

The torque box is sheet metal stampings in the form of a box attached to the bedsides, bed floor and the rear cab end floor stamping. It is what provides the rigidity in the body along with unique B pillar lower internals. When this is rotted away by cancer all manner of things can and do happen with the body and doors not aligning, the actual truck twisting and cracking. I junk any truck that has this severely cancered as it is a huge job to replace it.
