Re: Reproduction documentation

Dale that story does not jive what long time NCRS members claim as they have said in the late 70s a few members who worked for GM he gotten permission to go through al the records GM had at the time and came up with nothing in regards to build records. What they did get was option records and ECL codes. Even if there was records I cant see why GM would release them now. Just think of all the lawsuits that would follow all the big auction houses and such

Re: Reproduction documentation

All I know is what I read from sources. One former GM engineer said he visited the GM Heritage Center and asked about records. He was told, "Corvette records are only available starting when production was moved to Bowling Green in 1981." Smaller production divisions of GM like Pontiac and Cadillac interpreted GM's Records Retention Policy that called for periodic destruction of non-essential records differently and, therefore, retained such documents. It's been a few years since Jim addressed this issue at MCACN (2016) and I may have gotten the dates wrong but if NCRS members couldn't find anything in the 70s...

Len Williamson's "Tailfins & Bowties" book was done in 1989 and he got access to a lot of GM's records on Chevrolets for that publication. The figures from his book are pretty much the standard that many people rely on for data on production numbers, number of options, etc. He states that the Production Option Figures are what Chevrolet supplied him with at the time and are the only reports of its kind to exist. While the numbers of individual options (and colors for a number of years) are known, combinations of options, colors, etc. were not kept. As an example (he sites) in 1976 the Chevrolet Public Relations Department computed there were a total of (wait for it) 5,153,859,497,004,179,760 possible combinations of Chevrolet models, colors, trims, and options - with no two alike. Granted that's probably a computation for all 1976 Chevrolets but still the number is staggering.

Re: Reproduction documentation

Dale I think what more or less the records people found where the suppliers shipping records of what they supplied each assembly plant doing each model year for each different configurations of each option or model only part. The color records I think where kept by sales to determine what colors they would bring back each model year. I have seen scanned copies from Tonawanda of how many of each BB where shipped to St Louis. And what engines went into service.

Re: Reproduction documentation

What it all boils down to though is aftermarket window stickers are really just novelties, not proof and are in a way kinda bad for anyone that does have an original one because people will see it and think "yeah yeah, there's another one all darkened to make it look old and real"

There is no such thing as "reproduction documentation".

All the reproduced build sheets that are perfect have gotten by because they are perfect. (which most are not)
