Is there a "bare minimum" that all trucks would have, like the PTB stamps on a '69 Camaro?

Does it vary by plant? Has anyone documented any differences?

There's a real tendency in this hobby for people to just copy other people's markings. People also add new ones they've not seen before so that a lot of vehicles have -every- inspection mark you can imagine. So I don't want to get carried away, but I don't want to miss something as basic as the Camaro PTB stamps and have it be conspicuous by its absence!
Here's my collection of firewall marking threads from this forum:

I would ask you to read through those, as it will save me a ton of typing.

The only other thing I would add here is that the markings were not paint or chalk. We used a tire crayon. There weren't any specified colors, just whatever was provided - if you found a particularly nice one laying on the floor you would use that. Locations were defined more by internal plant processes (less by "helping a buddy out") and therefore varied by plant, and somewhat by shift and individual operator.

My own unrestored '65 GTO (built in September of 1964 in Pontiac Michigan) is pretty much devoid of any markings. There is a large "A" on the center of the firewall ("A" = "Starlight Black") and an "ok" partially obscured by the voltage regular. Nothing beyond that.
