A-Body chassis bracing- stock and aftermarket- what's good?

I have seen the cowl (firewall) to fender braces on a lot of mid 70s A bodies. I just got a pair off a 76 valiant for my 74 duster (not sure if they are correct length yet but I bet they are).
My 74 duster had them factory as well.

Probably a good idea to have them on any Mopar.

Also, seymourscamp a member here makes weld in sub frame connectors that are solid and great price.

Third you can weld in torque boxes. A small amount of grinding and welding required. The pre-fab rear ones are useful, the fronts could just be made up rather than buying.

Fourth you could add bracing tube from cowl to front frame rail. There are kits available for this and it is a bit intrusive into your engine compartment.

Fifth you could add a roll cage.

I have seymourscamp's 1x3" subframe connectors, front and rear torque boxes and will be running a pair of braces from the cowl to each fender and possibly one across from fender to fender to triangulate it in. Check out my build pics under my info if you want to.
