Exactly what makes a MOPAR a "Matching Numbers" car?

It's numbers matching if all the numbers match. Was this a trick question?

But like many have said, drive what you have and enjoy it. I have a complete blast every time I drive Vixen. If I'm feeling not so good, I get behind the wheel and everything changes. Probably going to a cars and coffee meet Saturday morning in Milledgeville if the weather holds out. Over 50 miles round trip.
