The whole De Tomaso world runs on a string and a prayer.
This forum and the registry are notoriously neglected. I say this with love, George of the forum and Chuck of the registry are providing a valuable service. Both are older gentlemen with other commitments and I do not expect anything more of them than what they already do.
I believe both the forum and the registry are one missed hosting payment (or bad health event) away from slipping off the internet forever. Both go months at a time without attention or maintenance.
I often think about setting up an automated backup, which would scrape the forum and registry each night and archive any new data. Of course, life gets in the way and I have not gotten around to setting this up.
Try hitting up a guy on Facebook named Michale Shortt. He publishes a competing registry (Pantera only, no other De To cars). He may have info about your car.
Note on the daily registry updates- there are some helpers who process entries which is why you are seeing updates but not hearing from Chuck.
