Some of the latest work on the underside. I've added torque boxes front and rear, added braces from the torsion-bar crossmember to the front chassis rails, and stitch welded the subframes and other key points.
Here's one of the rear torque boxes. I've also added a plate to the leaf spring hanger mount inside the box section formed by the torque box plate, same as the factory hemi cars got.
I fabricated the front torque boxes as they were much simpler than the rears.
