Remember, the body tag date represents when the production order was released, not necessarily when the car was final assembled. There is usually overlap at the beginning and end of each month. Some 06A orders were final assembled in July.

Norwood was shut down July 14-August 8. Guessing, they completed all 07A orders in the system. 

For each date seen on body tags, there is also a VIN range. 07A represents less than 2 weeks of production.

That tag will only 'fit' a car in the small 07A range.

Looks ok to me.

I had a similar Z/28-not a paint/trim combo you would want to duplicate.

Having spent a chunk of my working life in supply chain, here's my 2¢.

Planning starts very early, at the top. Marketing determines how many Camaros the plant will build for the MY. From that a Master Schedule is developed: Coupes, convertibles, base drivetrains. Some common options like A/C, power steering, are also easy to predict. From this, tooling capacity for parts common to all models are determined. Tooling capacity is mostly fixed; there's always overtime. That gets expensive and if not carefully planned can run the line dry later in the week. So there has to be inventory (safety stock) to cover; both at the source and in-plant. Inventory is a double-edged sword. Great when you need it, a waste of resources when you don't. Plant Managers were graded on obsolete inventory at the end of a model run.

For parts used on all builds, suppliers get the Master Scheule a few weeks out and produces accordingly: 3,000 frames this week, 4,000 next week. Drive train plants do the same; every week they ship base and probably a few common options in the quantities Marketing predicted. Since all this stuff takes up valuable space, Production Scheduling has to ensure they consume it. Dealers were encouraged and reminded to order their inventory accordingly. 

Some suppliers of common parts are required to be within a certain distance from the plant. I recall John Z mentioning that fuel tanks for Van Nuys were produced there, as were jacks certainly other components. Drive train components were not, VN had to maintain a larger inventory to cover. For 02A VN Z/28s the engine date to final assembly gap is 10-18 days; at Norwood it's about a week. One or two days is not unusual. 

Optional equipment was definitely a problem. Hard to predict and once locked into tooling capacity, nearly impossible to change. November 1968 Chevy stopped taking Z/28 orders as 302 engine production through the end of 1968 was spoken for. If an option was well under it's take rate, dealers were strongly encouraged to order it. When John De Lorean took over as Chevrolet GM, one of his first edicts was to discontinue any option with a take rate of less than 5%. 

You should try to find his book, "On a Clear Day You Can See General Motors." Much of Chevrolet's trouble was due in large part to excessive low volume options and poor production planning. One example mentioned in his book is 2,720 possible combinations for the 1969 Camaro dash cluster. I have been able to get to that number but believe it has an error. Actual number is probably 1,880. By 1972, there were only 96. 

Three p/ns listed 67-70: 3887033,3940977,3969903

Safe to assume it was. 1st year for the modern locking column.

Someone did a deep dive on it and came up with at least three versions of the sleeve.

reported VIN 124379N694129

N694129 was final assembled on or about October 3, 1969. Car has a non-original 12A [1st week December 1968] body tag. The upper dash panel has been replaced, breaching the factory VIN tag installation.

Both tags may not be original to the car; hidden VINs should be verified.

Car recently sold at the 2025 Mecum Indy auction.

L-R: #1 & #3 are out, #2 & #4 are good.

Checked the CRG db, perhaps not the most up to date info.

Earliest VN Z/28 was 02C, 4L tag.

Looks repro to me. The pad stamping is awful.

1111480 dates could be 9E13, 9H12, 9J24.
1112003 date 9G11.

A different car with the same VIN sold at Mecum Houston 2022.

POP decodes as a 307 4-speed with a 3.08 10 bolt axle.

No COPO 9561 convertibles.

Clevis in the lower hole?

Both COPOs included:

special ducted hood
heavy duty radiator
temperature controlled fan
special 4.10 rear axle
dual exhaust
14 x 7 wheels

These are not listed on the window sticker.

Both COPOs required these options at additional cost:

PL5 F70 x 14 raised white letter tires
Muncie 4-speed or TH400 transmission

These are listed on the window sticker.
