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

I don't have pics of cars I had 3 year ago, much less 40 years ago!!!!!
Amen. I bought a 69 Barracuda FB 340 Formula S new in 1969, and I cannot find any pictures.
When the dash vin matches the title. The rest of the numbers don't mean a dam thing unless your selling it to a purist. You can change the rest of the numbers on the car easily. Some of them never came with body numbers and warranty engines don't have the vin.

There are more guys out there with Corvette engines then the amount of Corvettes made
It's funny you mention Corvettes. They are probably the car MOST often misrepresented as matching numbers. Also, I was at the Mopar Nationals a long time ago, and there was a sign in front of a 70 Hemi Cuda convertible that said "20 of all the 10 1970 Hemi Cuda Convertibles ever made are at the Mopar Nationals this year.
Best thing I read all day...:) I am of the same..i am repainting my dart swinger 340 and driving it the next guy can paint it again any way he chooses LOL (Its a original C7 car) LOL!

Point is I am repainting it it will look presentable but will be a driver...not a trophy car or trailer car.
In 1992 I bought a 69 Barracuda project car. It was, more or less, a matching numbers car, but I did not care. It was originally the aqua color (Seafoam green), but I painted it F8 Dark Metallic Green.
Reminds me of the Johny Cash song where he stole parts from his assembly line job over a period of many years and built a car.
