You should talk to "Vito De Tomaso" a.k.a. Phillipe Olcxswnckzw and see if he has the original paperwork on your car.
He isn't a member of this forum, but may be reached by looking at some of the different Pantera / DeTomaso Facebook pages.
He might actually be able to shed some light on the questions you are asking.
Bring your wallet with you.
