Re: The build date project
Piecing together post #7 in this thread states that his 1970 Blazer s/n would be 0S138946 with build date of 12/69.
On a related note, both of the first two posts in this current thread mention that Blazers and Jimmy's don't follow the same truck sequence. I see that many (all?) 69 blazers started with a "B," but are there any more details regarding that sequence comment? I would think the last 6 s/n digits are chronological (per plant), regardless if Blazer, suburban, or truck. No? |

Re: The build date project
Here's some information. Blue font is useful, black is gibberish:
If you haven't already you might add 1972 Z161544 with a build date 04/19/1972. He posted it in 2013, fairly well preserved build sheet too - gave me something to work with. I went through this to attempt to confirm my well ventilated 72 Super Z146839 was built in Mar. though perhaps Feb. using the most conservative dates & numbers available. I'm only assuming the factory didn't skip sequences. Between March 24, 1972 and April 19, 1972 there were 7351 Z Chevy's built. That's the low end, divided by 27 days instead of 26, but a solid guide. That's 272 trucks per day and 8236 per month. Between April 19, 1972 and sometime later in April (Mystery April Date, "MAD") there were 2502 Z Chevy's built. If it's assumed MAD is the last day in April, then 9853 Z Chevys were built between March 24,1972 & April 30, 1972. That's on the low-end because I must be MAD, I mean the MAD is April 30th. Using the number 9853, that's 259 trucks per day or 7908 trucks a month for the period. Strictly a guess, personally I think this is somewhat misleading, not sure why I went here EDIT: Irony, I now see that Z164046 has a 04/28/72 build date. That was a Friday and 259 pencils out after all. Using the 03/24/1972 date (Z154193) for my 72 Super (Z146839) there's a difference of 7354 trucks. If March 1st is assumed through 03/24/72, then at 259 (minimum) trucks per day that's 6216 trucks. Bummer, still 1K short. If 272 trucks per day is used then still short 800. That said my sticker is faded, just at that corner too, go figure. But a magnifying glass says "/72" and I'm mostly sure the month is "3". It's so faded it could be gone next month. In my edgeucated opinion (90/10+) Z146839 is March 1972, though if you add it asterisk at your discretion.

I looked at two of the closest dates available with a decent spread: (3-24) Z154193 and (4-28) Z163961. That is either 34 or 36 days (34 if you consider Z154193 was built at the end of the day and Z163961 was built at the beginning of the day). Using those numbers, the average is 287 trucks a day. 287 x 24 (March 1 to Mach 24) = 6888 trucks. Backing up from 3-24, the earliest for March would be Z147305. Certainly Z146839 was built in either February or March. I'll add an asterisk, ? for the month and a note. Ill bet we can make better estimates soon.

Re: The build date project
My 72 C10:
A149453 With my truck being an Atlanta built truck and member Pro299 truck being an Atlanta truck built 3/72, I would assume mine could possibly also have a build date of 3/72. |

Re: The build date project
Reading some suggestions above, especially dates, you might consider a different format. Don't get me wrong, this effort by the two is outstanding, I'm reminded of the effort put into indexing the assembly manual, all we had to do was number 500+ pages
Perhaps this is a usable format. You can sort by any column and I think easier to manager by the task force. Edited: Date (zero=no day): March 0, 1971 Factory: Fremont71 (the reason for the year is for sorting - I like how you guy's separate factory & year & this will do that. See example below if interested.) Year: 1971 Perhaps redundant if year is added to factory, but strikes me valuable as a sort option) Chevy/GMC (gay man's chevy): Chevy, Suburban etc. (See post 119, might be better to add Suburban, Blazers as a note or as another column to sort by, e.g. "Other"). Vin: Zxxxxxx (Not sure you need "Z" but it sorts anyway). Notes: 71Chevy402 is a bum Flint70 Flint71 Flint72 Fremont70 Fremont71 Fremont72 On a side, if using Excel for example, the shorter the better. Sometimes it's necessary to put columns between columns to paste right, using symbols. For example: 01/01/1970...Fremont70...1970...Chevy...Z123456...Blank*...71Chevy402 is a bum. *Blank is a spot for Suburban and that, because blanks will throw off your paste. N/A maybe, but it's not as if you're registering every type. Edited again, cough). The list of your factories/years and that is a nice placeholder so to speak, but I wouldn't add them to your chart until a truck comes up. Just some suggestions, I'm a bum but long edgeucation in data structure & reports was enough to be happy to leave, with CDO and perhaps PTSD too, them (*&(*)&^ are crazy especially meetings. Quote:
We need a forensic to pipe in, there's got to be a chemical some sort.

I'm wondering if there are multiple layers of your sticker that maybe could be separated at the "date" corner. Perhaps the clear (that's no so clear now) top layer could be separated enough to reveal the next layer? It sorta looks like the layers became separated in that corner in your pics. Perhaps this could risk more damage than it's worth, so proceed with caution if you decide to do this at all. And I agree, it looks like a 3. |

Re: The build date project
This sticker is on a door I bought recently from a classic car wrecking yard just a few miles up the road from where I live. The date looks like 2/71 and the last six digits of the VIN look like 625107. Can't see the rest. Seems likely it is a Fremont truck.

Re: The build date project
Does it have the metal vin on the driver door jamb or the SPID on the glove box you could verify the last 8 of VIN?

If a five day work week that factory punched out 450ish trucks per day at the time.

Re: The build date project
Thanks a ton Keith, that is very valuable info for this project and gives us at least a rough idea of what we can likely expect. We’ve got enough in right now that we can get a really good estimate of some days or months, I hope to see that trend continue.

Re: The build date project
I have an update to the build info for my 1971 stepside SWB C10. I was shocked to find the very tattered build sheet still under the seat.
1Z622515. build sheet date of 01-21-71. This truck was shipped to Santa Fe Motor Company at 418 Cerrillios Rd Santa Fe NM. It originally went into forest service use and then was transferred to a volunteer FD in a small NM town. I purchased the truck from the volunteer FD guy.

Re: The build date project
I’ll get them added. I’ve got another I found in person to add as well.
Arctic man, that’s a pretty sweet find with the engine tag.
