Here's a link to Marti. He just needs the VIN number.
Your VIN breakdown looks pretty good except I'm pretty sure they started the numbers at 1000.
So yours would be 4972 unit built.
Somebody with a lot more expertise in deTomaso history might chime in and prove me wrong but that's my understanding.
