Matt,
Thank you for your kind comments (and Belair62 as well).
'58-'64 Chevrolet Passenger cars were assembled at a total of 18 different assembly plants over those model years (three of which were Fisher Body "only" locations, with no Chevrolet final assembly line attached). I think one of the greatest assets toward the "good" of the hobby is the fact that there was very little uniformity in the cowl tag coding methods used at the different plants. I even have evidence of option codes changing during one model year at the same plant. This inconsistancy makes it harder for someone to know what to have stamped on his "reproduction" cowl tag.
Jim's efforts should yield better results than our project can provide, since he is collecting build sheets. The build sheets contain information on every option, where our information is based on what was stamped on the trim tag. Unfortunately, not all of the options were coded on those tags. In the earlier years, very few were coded. And even in the later years, some plants only coded for one or two. Most plants did not code for the engine. So, Jim's efforts are really targeting the holy grail - undisputed evidence - the car's birth certificate, while our documentation is derived by "deciphering" of cryptic information based on a sample size to be statisically valid. But many build sheets contain those cryptic codes as well, rather than a simple "X" next to the option, or the actual RPO number, so it is possible that a combined effort will produce many more completed verifications of the originality of the Passenger cars. Please let Jim know that I am 100% in favor of combining efforts for the good of the hobby. That has always been my motivation since the beginning of our project.
If Jim needs any help with his "treasure hunt" regarding the Passenger car plants, I am offering my services (donated, of course).

Verne.
