Thanks for all of this info!
I've posted this question before, and met with the same fire/flood stuff. Anyone who has seen the aftermath of a fire can understand why fire/flood could be an answer!

As for the legality of releasing owner info, IF the data was still around and IF it could be retrieved and reformatted to a modern database, it would be a simple thing to provide only (example) column A (VIN) thru Column X (selling dealer info), and not printing/supplying Column Y, Z, AA, AB (Owner's name, address etc).

Sure would be nice to arm twist Mopar into using all the royalties from licensing repro parts and other vintage uses (shirts, hot wheels) for the historic group.
