There are methods of obtaining another VIN tag. One would be to find someone with a junk '68 Roadrunner and the owner still has the valid title and Vin tag. This is where a person's integrity comes into play. I wouldn't go that route unless I'd made certain the car WAS NOT stolen. Otherwise you'd be participating in perpetuating a crime. - And you'd have helped to separate an honest person from their car. It's a test of their own honesty. They do need to figure out if the car was stolen first.
