Shoulder belt attachment on 68 post Dart

That's good work but after you welded those nuts they weren't "grade 8" anymore. You could have just drilled and tapped the metal tab.
yes i do realize that bit of metalurgy now after watching forged in fire. ive de-tempered the steel, but iv seen how thin these GM body panels are and i still feel safer putting my kids in the old boat now that the sholder belts are in. the whole unibody style is weird to me after owning different trucks over the years with stout and thick frames... no frames on these cars is just strange to me still...
