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.

Welded in place.

Also picked up the CNC bent rollbar hoop.

Rollbar plan

Here's the plan for the rollbar. No more side intrusion bars due to them putting the rollbar in a more restrictive category with respect to MSNZ regulations.

Finished Rotisserie

I've finished the rotisserie frame for the car, with extra bracing, castors, and RHS tie bar.

Subframe Connectors

With the car on the rotisserie I could finish welding the underside of the floor to the subframe connectors. 

The torsion bar crossmember plate, note the gusseted torsion bar anchor, similar to what the 1970 Trans Am race cars had.

The other end of the bar, where it is slid into the rear chassis rail.
