Show us your crayon marks
 

So what's up with these seemingly random marks we find under the hood and on our firewalls and elsewhere on our trucks. What do they mean? Who put them there, and exactly when? Maybe if we compare a whole bunch of them a pattern might show, or at least some similarities may become evident.
So, if you got some production line scribbling somewhere on your truck, lets see it. Who knows ..we may learn something.
Below: Yellow crayon underside of hood on my '66. Also, on the same truck below the right cowl extension is what looks like the signature (in wet paint) of the guy who shot the color?

Re: Show us your crayon marks
 

I will get some of mine soon. In the meantime oem4me, it would be awesome if you could take many, many pictures of your truck to aid others in assembly for originality. You may have the best original truck in exsistence. This obviously would be at your discression. But there may may not be any better truck to go by like yours. Do you have an online picture account somewhere that you could do this? If so that would be great.

Thanks
Tom

Normally they relate to build sequence numbers (put there by line workers, in an attempt to keep everything in order) or inspection marks, indicating the item has been checked and approved - or - checked and repair is required.

Most large component assemblies, like tire/wheel assemblies, seats, rear axle trim and driveshaft, front suspension assemblies and engine/trans trim are built up in remote areas of the plant and then conveyed to the main line. It is essential that these items remain in order; if not, then not only is the affected vehicle messed up but everything upstream is messed up too.

They could also be lunch calculations, love notes, or ciphers for their "bookie". Anything is possible.

In the case of the two pictures you've presented - they are not like anything I've seen before on a vintage vehicle. The hood picture seems to indicate perhaps a bank of 10 special parts, and that your's was number 10 in that series (maybe a material tryout of some kind).

And - the cowl photo sure does look like somebody's signature. Never seen that specific one before but I wouldn't put it past someone to do that. In the Pontiac world there was a lady named "Linda" that became quite famous for signing the backside of the glovebox doors that she put together.

Here's mine: I followed my truck down the line (drove it off the line myself) and didn't remember this, but it was apparently build number "87" for that day:

They are no longer there but I would have expected to find a number 87 on the rear diff cover, on the inside of one (or more) tire/wheel assemblies, on the side of the frame and maybe written on the engine somewhere, all in an attempt to keep the flow of material in order.

Her's the only one I could find on my '65......

Re: Show us your crayon marks
 

Only thing I've really noticed on my stuff was sometimes the VIN or part of it is written on the firewall, but the only thing consistent I've seen was the color-"ivory" written on my 64 & two-tone on my other 64's firewall, seen many others with the color written on the firewall. My theory is many cabs were painted white, then body color added to the lower part for the two tones.

Re: Show us your crayon marks
 

Could be, although in later years the secondary color was painted first, taped off and then the primary color sprayed over the top of the masked area.

Re: Show us your crayon marks
 

Yes, I realize the rarity of an all-original untouched truck, and I do feel an obligation to share the details with those that are inclined to pay attention. Several of you guys have asked for pictures and I will provide them, probably in the form of a "build thread" so the content is not diluted with too many details from other trucks which may become confusing.
Now all I need is some quality time with my truck and a camera (which is not so easy to find these days). Thanks for your patience on that one.
On another note, even as well preserved as my 66 is, I know there are a lot of other trucks out there that are even better. They just belong to people that are not members here, or just prefer their privacy. Example: Recently, a 62 longbed showed up out of nowhere with less than a thousand original miles, virtually unused and in near perfect condition. They are out there.

wow, thats awesome.

Yea when you get time for yours that would be sweet.

Re: Show us your crayon marks
 

Id love to find an original truck with only 1,000 miles, bad thing is I use it like my daily driver. I just personally enjoy driving my vehicles no matter what year or mileage is on them.

Re: Show us your crayon marks
 

Two more "signatures" found in the same place, but on my 65 Suburban. To me, none appear to be from the same hand. Both trucks are from the Fremont CA plant.

Re: Show us your crayon marks
 

I need to get my camera to the shop to take some pictures of my 63. It has all the crayon marks still. My 64 had them as well, but I got a little too aggressive when cleaning the fire wall and you can barely read them. My 63 has them above the fire wall. Maybe bc the firewall is fawn??

Re: Show us your crayon marks
 

Very interesting thread. Waiting on more pics.

Re: Show us your crayon marks
 

Very interesting. The fact that they are all from the Fremont plant may be significant, since Fremont has a reputation for being a little more...."lax"....about the rigid protocols the plants closer to headquarters had to endure. Even more so as you get into the late 60's and into the 70's.

Re: Show us your crayon marks
 

#329 is written on my K20's firewall above heater, behind dash, on gas tank, on top of bell housing. It also appears to be stamped into the top edge of the firewall above the power brakes.

Re: Show us your crayon marks
 

Hey, that's pretty cool! That means my 66 c-10 was built on my birthday! Ha! no kidding. Not the same year though. Where did you get that info?

Re: Show us your crayon marks
 

over the years of collecting i found a guy that had the info. i have it for all the plants i can tell what month a truck was built . not the day . on my 66 the build sheet says schedule build date 10-29-65 . but i think my truck was built in nov of 65 last truck made in oct is 114952 . each plant had used there own number system mikem

Re: Show us your crayon marks
 

Hey Yelmer how bout #159704 `64 model....chevy ...by the way do any of the crayon marks match up with an RPO...?

Re: Show us your crayon marks
 

i need to know what plant ?

Re: Show us your crayon marks
 

1966 only sorry

Re: Show us your crayon marks
 

This mark is on the driver side of my 1970 CST truck, built in Fremont,California

Re: Show us your crayon marks
 

mine has a letter scratched into the original paint behind distributor on firewall

Re: Show us your crayon marks
 

Interesting thread here...These are mine. The yellow "Crayon" ones are on my hood (along with a similar marking that indicated the truck got new tires in 1979 - Dealership maybe? ) The other marking is similar to 70shortfleet's, same spot...didn't know it was there until I saw this thread and went and looked. My truck was made in Fremont, November '71. The "329" marking is interesting as it's the same number as 72kay20's...

Re: Show us your crayon marks
 

I HAD this one under my hood. The hood has gone to live with another member.

This one is on the firewall behind the passenger inner fender.

http://67-72chevytrucks.com/gallery/...7-A_Small_.JPG


It is continued below the heater.

This one is behind the distributor on the firewall. I kind of rubbed some of it off (OOOPS) trying to make it legible for the picture.

http://67-72chevytrucks.com/gallery/...8-A_Small_.JPG


This one is on the front of the cowl, dead center. I didn't even know it was there until I was sitting in the engine compartment trying to clean the one behind the distributor.

Re: Show us your crayon marks
 

I saved mine and after new paint I was able to go right back over the faint original grease pencil under the paint. It was a loaded 66 283 powerglide with factory air ps and pb and tinted glass.

Re: Show us your crayon marks
 

Fremont.....!

Re: Show us your crayon marks
 

b-4 and after

Re: Show us your crayon marks
 

That is correct; there is no correlation between plants relative to VINs or daily build sequence numbers.

These Fremont trucks are crackin' me up! Apparently the guys in the paint shop were pretty creative...

Re: Show us your crayon marks
 

I am not sure how to tell which plant my truck was assembled?
The engine was from Flint. How can I tell?

Re: Show us your crayon marks
 

Very nice Yote 1234! Like the color combination.

Re: Show us your crayon marks
 

the assembly plant is within the VIN. Search for a "VIN decoder" for your generation of truck (60-66?) here on this site.

Re: Show us your crayon marks
 

. . . .

Here are a couple on my 70's firewall.

The "B" in the upper right of the first picture is for the Baltimore plant.

The "635" in the lower left corner of the first picture is the job number.

The "AIR" on the inside of the right fender was to let the assembly line works know that this truck would have air conditioning installed in it.

Re: Show us your crayon marks
 

Great thread Oe...

I just brought home a '66 4K series GMC with a pile of options....from air brakes to suspension to HD wiring harness....
I am having probs with pic's right now, but I'll post up a few when I get over my problems..:lol:..
This thing has more ' Factory Graphiti ' than any I've seen so far..ie: "HDWH" ( maybe "Heavy Duty Wiring Harness"...?....duh I guess) on the underside of the hood....a bunch more on the firewall.
Pretty cool.
I really like the paint shop's ID work.

Painters are like Bass Players.
Plenty of self esteem....Maybe even a pain in the a$$.....but ya sure gotta have 'em.
Notice the mid to late eighties painters didn't sign their work....?

Huhh.

I sure do wonder how they new that $hit was gonna fall off so quick.

Re: Show us your crayon marks
 

bump with another paint signature.
