Dave, I just went and found a second book that I have and it does show the dealer codes for all the 64' Plymouth hemi cars. They are only showing numbers for the Dealers. Not names or locations. The first book by DD did not have them. Also, this book is only showing Plymouth. I imagine that if you want the Dodge information, you would have to buy the Dodge book. If you want, I could copy and fax the codes to you. Who would have the Master sheet of dealerships? Also, most of the cars went to different dealers according to the codes. It looks like dealers got just one car. They were spread out pretty good.
