I've been enjoying this thread too (from a technical side - not the arguments) because I've been trying to understand and document assembly plant practices in the 58-64 era for 25 years.
One thing my research can offer is the fact that (in that era) Fisher Body sequence numbers do not follow in the same order as the final VINs assigned. It is also not uncommon to find a body build date and body # out of sequence (based on VIN final assembly) with other body build dates.
For example, there may be 50 cars in VIN order that have a body build date of (let's say) 05A or 05B, then a car with a VIN 50 higher will show up with a body build date of 04D, and an expected lower body sequence number.
I'm not taking any sides in any argument. Just merely stating what my dbase of 1000s of 58-64s has proven. And like the CRG, my data is available as correlated information, (though it's not on line) and the individual owner information is kept strictly private. Unlike the CRG (or any Camaro research), I've had to deal with 15 different assembly plants over that time. However I can state that the process of order reception, VIN assignment, broadcast to the lines and Fisher Body build orders appears to be the same at all 15 plants, and it closely coincides with the procedures Kurt has described. There are some notable differences of course, but they don't apply to the 67-8-9 topic of this thread. (sorry if I've strayed)
