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

I think a lot of guys that grew up with these cars would love to have one with all it's original parts still in tact just like they drove them when they were young.
But that probably wouldn't mean much to the younger guys that didn't live through the Era.
...and that's ok
I grew up with them and I can assure you I did not even get mine home before I stopped at the local speed shop and bought every go fast part I could afford. Then take all them pretty box’s home rip that OEM crap off and bolt on go fast parts! But I grew up in a racers family so it was in my DNA. I absolutely love a 100 point restored concourse car. I admire the effort and work that goes into doing it. But line it up next to a red white and blue Sox and Martin rig and my attention is fleeting!
