Yes, the DD book is definitely the best place to refer to. That said, not all Max Wedge car VINS are in his books.

The bigger concern, a LOT of MW and early Hemi cars were race cars that have been hacked up and re-bodied over the years. You'll need to know a lot more than just finding the VIN# in the DD book to verify the car, but it's a good place to start.
