I seriously doubt that any judge will ever see the headmarkings on these trailing arm pivot bolts except, perhaps, those doing a Survivor judging.

Nope.
We just look to see if they look like they've been there 40 years or not. It's usually not hard to tell.

Regarding the leaf spring plate bolts; thought they were a white cadmium or similar, my originals (correct headmarks) sure didn't look like black oxide!

Rich -

For all practical purposes, there are NO black oxide bolts anywhere on a Corvette; the spring retainer plate bolts are phosphated.
