Hello everyone, upon inspection of the inside of the compartment where the gas tank resides, I encountered a grease pencil marking of 6-2-2 on my late 67 conv roadster 21,500+serial number. This number was located on the underside of the fibreglas panel that would cover the gas tank in the approximate area of where the antenna assembly is. Can anyone make andy sense of this for me? TIA Tony d

Re: Number interpretation: grease pencilled
Tony-----
Three digit, grease pencilled numbers found on underbody or chassis components usually indicate the "job number". This was kind of an internal numbering system used by the assembly plant to provide a quick and easy way of identifying subassemblies that were supposed to come together at some point. However, as far as I know, the job numbers went from 001 to 500 and then started over again. Also, they didn't have dashes between the numbers. The whole idea here was to have a simple, three digit number that could be easily scribbled on and used to keep track of things at a very basic level.
So, after that long-winded disertation, the answer is that I don't know what the numbers mean. Perhaps, some else does, though.In Appreciation of John Hinckley- Top

Re: John #29964, if available
Tony,
John #29964, who has occasionally been around here at the NDB, is someone that has first hand knowledge of the St. Louis production, assembly line, and numbers such as these. If he's available he could possibly give a definitive answer to what they are, or what they were for.
From some previous and similar questions that I've asked and some other information I've seen, my own best guess is that the numbers 6-2-2 would designate a "pull date" of June 2, 2nd shift. It was probably a pull date for the body, from assembly line production at St. Louis, before it was assigned a VIN and mounted to the frame. The reasoning for the "pull" would more than likely have been to have a repair made for an imperfection on the body, in the paint, or for damage.
Then again, some grease pencil designations such as those may not be clearly defined what they were for anymore, even beyond the first hand knowledge still available. Hope this has helped. TBarr #24014- Top

Re: Number interpretation: grease pencilled
My '66 coupe has a three-digit number written on the underside of the body, facing the front of the gas tank. It is either a "V" or an "X" (where the cross of the two bars is very low) and a "207". I had always heard, as Joe suggests, that this is a job number. Anybody know if the first character was usually an "X" or a "V"?

Re: Number interpretation: grease pencilled
Tony,
My interpretation is the same as that of Tom Barr's; i.e. it is a date, sans year, with the last digit being the shift.
I reached that conclusion after finding several such "dates" during body-off restoration of my '70 coupe, and the fact that some are very close to, but all precede, the build date of the car. Comparison of the "6-2-2" marking with the build date of your car may provide you with similar confirmation.
As you said, the sequence number is the same easily recognized three digits all over the car, sometimes followed by marks indicating car options to install in that area. My '70 had "426", "PB" (power brakes), and "UA6" (optional alarm) on the left splash shield area, and the rear floor area had "426" and "AC" (air conditioning)
Let us know how your build date compares with the "6-2-2" marks.

Now Let Me Get This Straight....
In Noland Adams 63-67 Guide on page 45 there is a photo of a '67 tank sticker, which refers to the large hand written number on the right side as the "job number" (200). My sticker looks like that. On pages 22 & 23 are pictures of the assembly line, with "jobs #357 & 358" (with a grease pencil) on the front and rear of the fiberglass.
After reading all of the posts, I still don't get. It seems to me that Noland is inferring that both the "job numbers" on the sticker and with grease pencil should be identical. Any theories or explanations? Thanks, Patrick- Top

Re: Now Let Me Get This Straight....
Everyone seems to have a 3 digit number grease pencilled on the body, myself included. My understanding is that the job numbers on the tank stickers were rolled back on the first day of each month to Job #1; this way they could easily keep a tally of the months production. As someone else mentioned, the number on the body could have been a subassembly job number which went to a certain point at the plant, there might have been a body job#, a frame job#, and a final assembly job#, which was written on the tank sticker when the body was dropped on the frame.
Obviously, there had to be job numbers with only 2 digits on the tank sticker to keep a monthly count of the car output for the month. Just a thought. Patrick- Top

Re: Now Let Me Get This Straight....
Patrick,
I am trying to understand the source of your confusion, so don't take it wrong if I have misunderstood what you're saying: I don't think Nolan Adams was trying to say that the tank sticker with the job number "200" is in any way related to the jobs shown on the assembly line. I believe he is simply using both photos to illustrate the three digit job sequence number.
As you said, all our cars have a job number. On my car, the job number appears in four different places with, as I have said, marks indicating the car options that are relevant at that location. Incidentally, I believe job numbers less than 100 would probably have been marked with a preceding zero, but someone with a low job number would have to confirm that.
As to the marks Tony asked about, I have my own opinion because it appears in a date format (i.e. with dashes between digits), but like Reba said about their job/VIN, it may be coincidental with my build date. I hope Tony will get back to us with that build date. It will help to expand our knowledge.

Re: Now Let Me Get This Straight....
Chuck, as you said, I really don't necessarily agree that the job numbers on the fiberglass are related to the job number on the tank sticker. My tank sticker clearly indicates job #30, with no preceding zeros, and has a build date of July 5th, and not counting weekends and the July 4th holiday would seem to support my theory that the job numbers were set back to #1 on the first day of the month, and yet there are 3 digit "job numbers" on the front and rear fiberglass. I know the car has never been lifted off the frame. What do you think? Patrick- Top

Re: Now Let Me Get This Straight....
Patrick,
Ohhhhh, now I understand your confusion; you have conflicting data in front of you.
Unfortunately, I never had my tank sticker, so I don't know what job number was on the sticker. But, I always believed what Reba said, i.e. that there was only ONE "job number".
To get to the bottom of the apparent discrepancy, you may have to do some detecting, and ask some hard questions. For example, did you personally drop the tank and remove the tank sticker yourself, or was it given to you by the person who sold you the car. I am not saying your car isn't completely original; what I am saying is that I suspect some people use copies of tank stickers from other cars to make a car appear more "documented". If you removed the tank sticker yourself, then maybe we are in the anomoly realm.
Before I bought my present car, I was looking at an air conditioned LT-1 at a Corvette dealer in Houston. He claimed the car had good documentation, tank sticker, etc., and he wanted a commensurate price. After studying a xerox copy of the tank sticker, I noticed the car had power windows and the tank sticker did not. When I asked about it, he was flustered at first, but still claimed it was an original car. He said the previous owner was always improving and tinkering. If it was attempted deception, it was a pretty poor try, but it was enough for me; Being inexperienced with Corvettes, I wasn't about to sink $28K into a car that didn't match a tank sticker presented as original. Moral: If the car was an original car, he would have been much closer to making a sale without the tank sticker.
Let us know your progress.

Re: Conflicting information....
Patrick,
I've asked the same question here at the Discussion Board and so has a few others. Not all the Archives are available for reference, but one or two good responses and sources have been saved there, when eventually those can be referenced. I don't remember the year of your car, and that may have a bearing on it, but it is more than possible, even probable, that all three numbers, the VIN (last 3 digits), the hand written grease pencil job number(s) on the body, and the number hand written on the build sheet will not match any of each other.
From what I remember about the responses to the hand written number on the build sheet is that it was a different system of tracking, an internal office system, and was marked on (and through) the page(s) before a copy of it was applied to the gas tank or received at the assembly line. Until I can find a further verification then I hope this doesn't confuse things. TBarr #24014- Top
