Alan, thanks for the info. The car I'm looking at does not have the original engine or trans, and i'm pretty sure the seller does not have the window sticker (he has not mentioned it to me).
Is there any other way to verify the original engine and trans combination?
Just from observation, in appears the order number was sequential in loose relation to the vin across model years. 69fastfun's Feb production 69 has an order number beginning AYR. I've seen Feb 70's with ET. My Jun 70's began FM. Alan's early 71 begins GBT and garage ghost's late 72 begins TAM. Some numbers are 3 letters followed by 3 numbers, some are 2 letters and 4 numbers. Was the order number sequence corvette only or did it include all Chevrolet/GM products?

John Hinckley shared with a few years back that orders were Chevrolet with no organization as to who got what. The only exceptions were special editions like Pace Cars and Collectors in later years.
Hi Gunther,
The sequence is year, month, day. In 69 only 1 year digit was used, later on, 2 digits.
To my eye the first digit is an 8, not a 6. (look at the shape of the 6 in the order # on the same line.
Then it makes sense. 8/12/06
What do you think?
Regards,
Alan
...Interesing insight. Now share how you know this...
The 1969 Stringray Guidebook by Rick Bizzoco explains the origin of the order number in Detroit.
If memory serves, JohnZ had an article in Corvette Enthusiast explaining the 7 page carbon, how they were burst, and how the upper left corner could be missing as a result. I PMed him once asking where the separate pages of the 68-72 sheets were routed. I'll hunt through my notes and dig up his reply. I recall the Chassis Line got a copy; each of the trim lines got a copy. One of the two copies with the VIN went to the front office.
Your article covers the change in tank sticker format from the old portrait type (68-72) to the new landscape type beginning with the 73s. With the landscape type, they appear to have printed as many copies as they needed. No carbons and no bursting.

I read it as December 6, 1968.

Great book for the early C3s

Same lines were used through the balance of C3 production at St Louis, engine dress and Final Inspection were another two. I've picked up a few inspection sheets but not sure they titles reconcile with production lines. They have like mechanical trim #2 and #3 and Final Effect.

I'm working on a Part 2 Buildsheet article for the 73-82 period. Have spent some time on the Chevelle forum where the Landscape style buildsheet was in use for Chevelle production from 65 thru 72. The Chevelle Fremont plant was the lone GMAD plant using the landscape style manifest at first. By 1970, all Chevelle plants were using this style as GMAD tookover plant management. By 73, GMAD was running the St Louis plant as well reflected by the landscape style manifest.
"The Body Shop and Paint Shop used a "run sheet" that had a line for each unit with the job number, style, color, and body-affecting options by RPO number.
After the Paint Shop, each unit had a "Broadcast Copy" printed on teletype machines (which became a printed "manifest" in about '72 or so)...
Beginning of the Hard Trim Line
Instrument Panel subassembly
Rear Suspension subassembly
Frame Line (also used on the Chassis Line)
Engine Dress Line
Final Trim Line"
The missing number from your tank sticker on the top right hand corner is:
170533 which is the same number printed on the top right hand corner of your window sticker.

VERY nice tank sheet!
The only other place that I've seen the order number is on the Window Sticker. I'd think it appeared on other paperwork too.
Here's the tank sheet and window sticker from my 71. Order #GBT168.

Alan
