Factory chalk/paint marks
My truck had no underhood markings of any kind that I could find during teardown. Not even under the AC/Heater box.
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!

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. K

Re: Factory chalk/paint marks
This was a firewall marking on our old '68 step side.

Re: Factory chalk/paint marks
the bare minimum I've seen is model number over the a/c or heater box. But most I've seen have had a bit more. Good threads above.

Re: Factory chalk/paint marks
Thanks, I hadn't!
I think I'm going to go with the model (CE....) over the heater and the 3-digit over the driver's side. That's enough to have some and not be over the the top. I guess worst case it wipes off, unless it's a paint marker! My model number is CE26034 My color code is 592 (but that's the 2-tone code) If the body is two-tone, does anyone know if they wrote the body code (508 DK BLK) or the triple-color-code (521 WHT & DK BLK & WHT)? I assume the latter but do not know. Does anyone know if Fremont (ZZ) was normally white or yellow in 1970? One of each for contrast?

Re: Factory chalk/paint marks
On my 68, it has "2T" on the drivers side firewall for two-tone as opposed to the paint code.

Re: Factory chalk/paint marks
T for Trim
2T = Z62 4T = Z84 Leddzepp, does your truck have a model number on it? Is it from Fremont? Dave the color could be any, red, black, white, yellow. Fremont trucks sometimes had a number stamped into the crown of the firewall and the same number written on the tranny tunnel. Pic below. They also were generally less marked up compared to a truck from St. louis or Flint. (Your second Z is for 1970)

Re: Factory chalk/paint marks
Im not sure Bruceman, I will try and get a pic later tonight when I get home. I think the model number is on the passenger firewall iirc. This truck was built in St Louis, although it has been in Cali. since it was bought.

Re: Factory chalk/paint marks
Firewall pics. There are markings on the core support, drivers side, but I added a dealer/factory recovery bottle that covers it now. The rear x-member also has the model number written upside down as you pointed out above.

Re: Factory chalk/paint marks
Thanks for posting those leddzepp. I see your truck has the 6 in the center. Several St. Louis trucks have that 6. Sometimes it's by its self and sometimes it has the A/C mark in front. I have no idea what it means. Truck in post 8 has the 6 also. Probably a St. louis truck too.

The PVI is assigned as soon as the dealer order number is delegated to a particular vehicle assembly plant. The PVI is the primary identifier, typically through the body shop, until the VIN and GA sequence number are assigned. At that point the GA sequence number is the "gold source". Nobody cares about the VIN in the vehicle assembly plant (other than getting it on the right vehicle). For most plants the build order can be shuffled after body shop (before paint) and again after paint (before trim), in order to level work load due to option content or protect against part shortages. In those cases the GA sequence number will be something different than the PVI. Fremont built straight through (no shuffling) so that's why the PVI will match the GA sequence number. Quote:

The frame is then flipped over and continues the rest of its journey right side up. K

Re: Factory chalk/paint marks
My 69 with 9,600 miles on it has the wax#'s on the firewall, on the frame under cab, drivers side, and rear most cross member of the frame, facing the rear. John

Re: Factory chalk/paint marks
That's "2T", which is the trim level.

Ideally you would see that number on any component that is loaded or built up/trimmed out remotely and then conveyed to the main line in sequence: hood, fenders, rad supt, engine, trans, seat, front and rear axles, tire/wheel assemblies, etc. K

My 72 has what I believe to be the PVI? written next to the brake booster and not in the tranny tunnel. I suppose this is just some variance.
