Used the "search" feature to try to figure out my build date but I get a couple conflicting answers. After looking at about 50 posts I think I'll just ask the question.

The build sheet shows my '92's build date as " 92/169 ". Some posts say this means the 169th day of 1992 (June 17), others say it's the 16th day of the 9th month. And I think I saw something saying that would be the 169th day of PRODUCTION for 1992's. Production started....when?

Thanks!

Hi Don,
Try a vin search and see what date you get, then you can compare and figure it out. Let us know what the results are.

I believe the plant uses Julian dates for the build date. But that date is not necessarily the day the car actually started down the assembly line. I believe it's the schedule date (when the VIN was entered into the production sequence). Actual production of the car could be a couple days later.

Given day 169 was late in the model year, what are the last 6 digits of the VIN? A high number would indicate a late production car. The last '92 sequence number was 119977 and most likely came off the line in late July or early August.

My old 92 'vert had a build date of 92/107 and I believe that was the 14th of April.

 

I entered my VIN for my 92 and it said not all vins are in the data base.

 

I know a lot of folks are understandably reluctant to post their whole VIN on line, but given THAT info I'll do it - 119972!

But that still does not help with the "169" built date - Julian would be June 17 (too early?), or September 16th (more likely?). "Time" BTW is 10:19.

 

From the last 6 digits you posted, it sounds like the car was built on the last day of production. with only 5 cars behind it.

My old '92 was 114605.

The format of the date as it's printed on the build sheet (92/169) is typically that of a Julian or Ordinal date value. It's also common to see something like "92169" (no slash) as an alternate format. We used that format in the IT shop I used to work in.

One thing you could do is to contact the NCM and ask if they know what the last production day actually was back in 92. The Assembly Plant closes for a period of time after the last car is built so they can make any changes to the production line to gear up for the next model year. And it's also a time where a number of employees take vacations.

 

compine.com says your build date was July 16. The 1 millionth Vette was vin 119134 and was born on July 2, so I think compine is correct.

My vin is 115057 and was May 13

Looks like they averaged 2500 a month, so 100+ a day would have the same build date. Last one went out on or near your date, so looks like they produced from Mid November 91 to Mid July 92.

 

What is the average daily output? And do they run full bore to a certain point and stop, or would the last few cars be built at a more leisurely pace? And since you say they started building '92's in November, would that mean "169" was the 16th day of the 9th month of production?

 

Well, my 95 is 1 out of 2 and my 96 is 1 out of 116.

Now, I feel special

yeah right

 

Don, does your year have the label on the latch-edge of the driver's door with the month and year of manufacture? My '84 has a "Sep 1983" date on it's label..

 

Ratman, I had not thought of that sticker when I posted the question but yes, it does show "07-92" on it.

So 16th day, 9th month of production would give a "169" build date. On the other hand C4Cruiser has a date of 107 which using my example would be May 10th. But he's figuring an APRIL date. Hmmmm....

 

How reliable is this website as to build date ?? Anyone compared result from site with Build Sheet???

Interested in any comparisons..

Vetteman42, Socalman ran that Compnine and came up with July 16th as the answer. Since the build sheet I got from NCM shows "169" it appears the web site is - in this instance anyway - right on.

And as others on here have noted, that's not the date they turned the key and fired it up, but when the ball was started rolling by entering the production info into the process.

It would be interesting to see a listing of VIN numbers of the cars coming off the line to see how close the actual production is to sequential VINs. Numerically mine is the 6th last 92 built, but it could have been closer to, or farther from, the last car ACTUALLY made.

 

Most sequential numbers do come off the line in that numerical order. The only real difference in where the car actually were on the line would be the mixed-in ZR-1's. They had their own VIN numbers but were intermixed in the production line. It's also possible that cars somewhere on the line that would have been removed for some reason (failing QC, missing a part, or a special order car like a race car).

When I checked the VIN of my old 92 on the compnine website, it said that the build date was May 8th. On a Julian (Ordinal) date calendar for 1992, May 8 would be 92/129 as 1992 was a leap year. But my build sheet says 92/107. The door sticker on my car (like the one pic) showed an 04/92 date. So that's a 3-week difference.

I would suspect that there is more error in the compnine website that there is with the actual GM data as printed on the build sheet. In any event, Bowling Green would have been done producing 92's sometime in late July.

But again, that date on the build sheet is not necessarily the day the car actually started to move down the line. There would be weekends, holidays, maintenance shutdowns, and other things that impact these dates. And the plant could have been running two shifts which would have increased the production rate. Or may just one shift which would have lowered production numbers.

 

C4cruiser, what you just said works out almost exactly in my interpretation of that code. Your code is 107 - I would take that to mean 10th day, 7th month of production. Someone said they started building 92's in November '91 so May would be the 7th month of production. So we're dealing with a May 8th vs May 10th discrepancy which certainly is not much - one could be computer input, the other the day the build started, or something like that.

 

My 1991 was built on july 11,1991 it was 400 cars from end of model year. Im sure November wasnt the first 92s built... also i checked the code.. 107 would be the 107 th day in 1992 hope i was some help.

 

Ed, the problem with that is, my "169" code would be then be June 17th, and we've pretty much agreed it was a July build quite near the end of production. The door sticker Rat-man suggested shows July on mine. And that Compnine web site is showing July 16 also.

Theories, theories. We need a definitive answer on what that number represents and how it is derived.

 

I read my build sheet.. the Date is 91/169 on it ... I was on the forum here a few years back with someone who actually assembled cars at Bowling green. He said that is the date the car is started on the line. [takes 2-3 weeks till completed]. the C4 starts out as a sheet of paper ..then frame..etc...all the way up to final inspection. My date on build sheet is 169 the 169th day of 1991. its june 19th.... but according to Bowling green my car was completed July 11,1991. My door sticker says 7/91 too. Kinda makes sense??? the gap was 20 days,counting weekends and stuff?? I hope im some help. Thanks Ed

 

Whatever the case it's cool to have a near end of production year and also close to the 1 millionth
