Re: The build date project
Ok guys, I’ve got all but 8 of those added today and got another list by pm that I’ll try and get too tomorrow. 1 big thing that will help we are finding is if you can post the MAKE of the truck as well. For the plants/years we have info entered it’s easy to see the difference in the sequence number format in the same year and plant, Chevy vs. GMC. For the plants/years with no info recorded it’s more difficult to know whether we are messing with a Chevy or a GMC. Thanks guys and we will get them updated soon enough. If you seen any irregularities between the two lists please pm us so we can figure it out.

Re: The build date project
This is really turning out, thanks for the effort. Still can't zero my 72 Fremont 146xxx down to a single month, but pretty close. Fremont was really pushing them out too, they may have approached 9K a month at the time.
Any chance 71/72 Chevy Fremont trucks were the most plentiful? ![]() Without specific dates you can't tell how many were produced per month, but here's where my 72 C20 would fall for Fremont, as a guide.......146xxx would be Feb. or Mar. 135708 Jan. 153077 Mar. Increased by 17369 161544 April Increased by 8467 164046 April Increased by 2502 168790 May Increased by 4744

Re: The build date project
Personally I wonder if it’s more that the Fremont trucks were being mainly sent to dry climates being they were produced in the west, and are the ones that have better survived.
I’ll get on the additions this evening. Also, the original thread has been closed.

Re: The build date project
It may be helpful to reference the source of the info when updating the first two threads. For example, noting if it came from a PM or which post # the info is pictured.
Here's one I found that may be slightly out of order with another data point (post #68). 72 chevy 2Z163961 I believe build date shows 4/28/72 |

Re: The build date project

Does anyone know how the "job sequence number" (see very top left of build sheets) impacted production? The truck in post #68: Serial Number: 2Z164046 Job Sequence Number: 03114 The truck in post #89 Serial Number: 2Z163961 Job Sequence Number: 03x09 (guessing 03009, or less likely 03809) It is interesting that even though the serial numbers are 85 numbers apart, the job sequence numbers appear to be at least 105 off from each other. I'm wondering if it is possible that a certain batch of serial numbers started on a given day and then received their production date when finished assembling. If there were multiple assembly lines, perhaps some lower serial numbers could actually have a slightly later assembly completion date. ...just thinking/guessing out loud.

Re: The build date project
These are from an old thread on the board. Most on that thread appear to already be captured within the first two posts here or have illegible pictures.
70 GMC; SZ68109; 3/70 70 chevy; 0Z142486; 2/70 70 chevy; 0S138xxx; 12/69 70 chevy; 0A158364; 7/70.....this one was already on the list but had incorrect date. 72 chevy; 2F355033; 3/72... Original decal and reproduction decal found at link above. Last edited by 402Bowtie; 12-08-2020 at 09:36 PM. |

There were I think 603,347 Chevy trucks (Blazers, C10s, K20, suburban, etc) produced in 1972 (according to post #6 in this thread...I added up all the 1972 production numbers). It appears Flint produced close to half of those 600,000 Chevy trucks based on the serial number referenced. In other words, Flint produced the 255-thousandth Chevy truck in March of 1972, and production likely went into June or July. Last edited by 402Bowtie; 12-09-2020 at 02:15 AM. |

Looking at March numbers for the other plants, Flints numbers would have to be about 71% higher. But if Flint produced half of the entire 72 run, this percentage would make sense. However, we do have a Flint jamb sticker 4/72 with a sequence of F163780. I have added the F355033 and will continue to try and reconcile this. |

Re: The build date project
Added today’s, I started adding post numbers to the entries. I will go thru and update the rest of the entries as I get time. I still need to add a pm list I’ve got, hopefully tomorrow.
