Yes, I checked the register. I found that the vins on either side of my '73 2591342 which I bought 45 years ago are not chronologically accurate. While I await a response from Classic to confirm, and knowing that the production date is most likely between april and june '73, I thought I'd try here to interpolate a date if anyone else with a vin close to mine has an accurate date from Classic so I don't miss the birthday. Thanks for your help!
