uncommon copo found

[JQ]

Don't know if it's been asked yet but is their a BE rear end in it. What suffix is on the front pad? JQ

I understand that the special cars do not follow any set sequencing. What I thought was that the "normal" ordered cars may have. So after the order was accepted by fisher (body number assigned) they would have been built relatively quickly. So we could determine more or less when the COPO orders were accepted by Fisher by comparing the COPO body numbers to regular cars body numbers.
I will post this topic on CRG to see what JohnZ has to say about it.

The copo cars were not built 'quicker' or 'special' from the research that I've done. Don ordered the first batch of copo novas in early Dec. of '69, and they were not built until the last week of May '70. I think there was a strike in there somewhere, but even so, they didn't get preferential treatment. Let us know what JohnZ's reply is, it is interesting to learn about the scheduling details within the GM plants.

I thought it was a known fact that the 69 COPO 427 cars were done in batches due to limited availability of some of the components(BE rear mainly). Kurt S should have more info on that and Jim M can probably add to it. Therefore, COPO 427 cars tend to be grouped together by the NOR sequence number. I don't know if particular dealer orders were kept in order vs other dealer COPO orders though.

It is my feeling that a certain dealer could have his batch of COPO Camaros, ordered at the same time, grouped together by the NOR bodynumber.

Shortage in components like BE-rearends would, more or less, group different dealers COPO Camaro-VIN´s together.

Marlin,
I am sorry that I wasn't specific... I was not referring to Nova's at all, I have no idea how they were sequenced built etc.
I was referring to the past comments about Camaro's and how body numbers were assigned and how the bodies were not released to be produced until the parts were available, which is why the body numbers are much lower that the "normal" cars built during the same week as the COPO's.
I have the cowl tag numbers from a Z28 03D car and it has a body number that is 30,000 units higher that the COPO built the same week.
What that tells me is that the order for the COPO was accepted about 2-1/2 months before hand.
What do you guys think?

I was using the Novas as an example to show the time span between ordering a batch of copo cars and GM actually building them!

As I said previously, referencing the body number to a build week is not a reliable comparison. In one of the prior examples, a later build week of cars received earlier body numbers, and vice-versa!

The body numbers are not always linear in relation to build week.

I like to use the copo novas as an example: The first 15 deuces have the earliest body numbers, and have build dates of 06A. The next 15 deuces have sequentially later body numbers, but have an earlier build date of 05D! So, the earlier build week does not necessarily indicate a lower body number - strange, but....

Very strange. But I have witnessed this personally.

That billedle is a bit strange eh?

The COPO Chevelles do wacky stuff like this also...just about the time you think you see a pattern, you get some cars thrown in there that go against the rule...you'll see some 289xxx cars done in 07D, but then some 283xxx cars in 07E...with the VINs naturally way off as well...

Like Rob points out, there are inconsistencies between body numbers and build weeks & between body numbers and dealer orders.

I think it's equally fair to say that there are also consistencies in the numbers as well. I personally believe that when you see 3 out of 5 sequential body numbers going to one dealer, that the probability is pretty good that the other two went there as well - and, if those 3 cars were copo's, there's a good probability that the other two may have been as well.

The point being, the body number, build date, and dealer order info is good to have - just not conclusive, and justifies further research.
