I have a 67 GT w/390 4 spd that I received as a result of a bad loan.The vin # tells me it is a fastback,built in San Jose, with the 390. It has the GT option with the foglights and GT stripe.Where do I find more info to insure this is an all original car? Engine,tranny,GT option serial or code #'s? It also has the 9" rear end.The car is in beautiful shape w/58,000 showing on a working odometer.I know what the loan amount was that was forfeited for me to have the car. I do want to sell it but I want to make sure I know what I have and what it is really worth.Also, should there be a build tag or something riveted to the driver's door jamb on a 67?
