Dave makes sense, but I don't completely agree. On my car, almost everything but the shell is new. And some of it is repop panels or parts from donor cars. There is almost nothing attached to the shell that came with the car originally. But, the VIN is still riveted to the dash and stamped on the aprons. My car only sorta resembles the car that came from Ford. I built it "from scratch" using a collection of reconditioned / modified parts from other cars or reproduction parts. It's almost as much a "kit car" as one you would build using a Dynacorn body as a beginning. If you buy a Dynacorn body, and use it to replace the body of another car, but in the end little or nothing ends up coming from the original car, is it still OK to swap the VIN? In the early days, the engine was the numbered part and the car was attached to it. Today, it seems that the body shell is what defines the car. Once you replace the shell, I think you crossed the line. At that point, you need to declare it a "new" car that is quite similar to an old one. The street rodding community is all to familiar with this dilemma and there are laws in place to deal with their case. They don't have to register their cars as "new" or abide by the regulations of new cars. Using a DC body is just like building a street rod. My car is a street rod, of sorts.
