SS Hemi Dart 'cuda frame stiffening?

[Ol'forest]

What if any frame stiffening was done on the Hemi A-bodies? I would expect torque boxes, but did Hurst install sub frame connectors?

The info I have here is from old pics from ´68-69.
Torque boxes only in rear. Auto and stick cars. There may be exceptions here, and very few may have had them up front.
Chrysler expected the new owner do what he seem fit, but NHRA did not allow any modifications on the car the first couple of years, so no sub frame connectors yet.
Reinforcement above the Pinion Snubber area I have seem, but nothing from Hurst.
