Hey Pete, no problem.
I'm actually looking at an ex-drag Camaro that's had them switched & I'd want to register it by the firewall # instead of the dash vin. You have to wonder why someone would go to that trouble for a drag car.
What if the reason they were switched was because it was stolen? Or, what if it's a special car & the digets are on a restored COPO or Z 28-could I get the tags back? I can't put money into a car that I might not legally own.
