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

I remember the episode. Mark found, after he got into its resto (which seems to always take him many years) was that it was rebodied. Or lets just say, the vin tag does not match the body!!!! The vin # on rad. support and back side of car were not right. NOT good on a car you will spend what? maybe $80,000 paid to Mark??

The anal resto guy wants everything oem right down to what they seem to think is dated in the correct window. and for sure the vin on eng., trans if what, late 68 up. ok Then there are the so very few survivors that still have all or most all their parts and pieces that came on it from the factory. Dated air in tires.

I personally enjoy knowing what is correct as to how they came from the factory. It does not mean every car I touch as to be built to such! Some cars deserve such. I used to find a few "matching #" cars back in the 80s, fewer in the 90s and hardly ever now! Now days,,, I always look for rollers that I can build as how I want without fuss or criticism. Well actually, the older I get the less I give a chit who critizes!
Try $120K. I had to work on one of their "restorations" after the car was shipped to the owner in Chicago and had some serious issues. It was his dad's car who bought it new and totally numbers matching, which means the VIN, both hidden numbers on the body, plus the engine and trans matched the VIN also where stamped. Unfortunately both his dad and mom died before it got finished, and he wasn't a car guy and had problem figuring out how to start the carbureted car! Nothing else matters except the parts with the VIN's on them to call it matching numbers. I have had a couple of cars that did not have all the numbers stamped where they should be but were totally original one owner cars before I got them, so the factory didn't get it right every time...
