Not sure this one is helpful. Can anyone read it?
72 Blazer; 2S105697; I think the date is 8/71, but maybe this is one for the discard pile since it is hard to read. |

This one evidently had two build sheets.
72 chevy; 2Z128188; 12/10/71...or at least 12/1x/71 First build sheet shown attached in this post. See following post for 2nd build sheet. |

I think the blazers and suburbans should be mixed in with the other serial numbers (and maybe noted in parentheses as you have been doing). It appears to me that every model was mixed together as it came down the assembly line. Any proof otherwise? You guys are doing a great job compiling and laying out the info, but I'm going to nitpick a little (it's the engineer in me): -Fremont is spelled with only one "e." -Under each year and make, I think we should keep the list sorted purely by serial number, not by date. ie. Don't intermix 2F1 with 2F3. Sorting by serial number I think will make it easier to look up our build dates in the future when our list is bigger. Regardless, I'll be looking for more data points to add! |

Of course we could just utilize 2 sorts for Flint? I am sure we are yet to identify all the anomalies. |

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. |
