I was about to publish a club member's research on how to interpret numbers on the data plate/fender tag of a particular year/model in our club newsletter. This is information not readily available from factory publications, but rather compiled by looking at a number of cars' data plates and extrapolating what numbers on the plate represent by cross-checking options on the cars with existing lists of option codes, etc. Other people have likely done the same thing, but there is no "one-stop" source for it. Now I am getting pushback from the "old guard" of the club, who fear this information could be used to create counterfeit cars. On the one hand, this has happened (though not necessarily with this particular year/model) and the club has been involved as an authority in some cases. I don't know how helpful having this would be to a counterfeiter since the factory build records are available from a couple sources, so if a car showed up with options or colors that didn't match the build record that can be checked. I guess you build a car from just a VIN tag and then get a "correct" data tag for it, though you can tell an original from the readily available repros. To be fair, the club will release this type of information to individual club members in order to authenticate a particular vehicle. So, how does your club handle this sort of information? Thanks
