Thoughts on this car for a project with my pops

Is the fact that it is body/engine vin matching anything special?

No, it isn't because it is an impossibility. The VIN only appears in one place on a 1966 Mopar, the VIN plate in the door jamb. The number on the fender tag and radiator support is the Shipping Order Number. The two numbers can only be matched with a broadcast sheet or IBM card. The block will be stamped on the front under the left head, but that will not contain the car VIN, either.

BUT, congrats on the project.
