1966 Dodge D/Dart ~ 'Mystery, Myth and Misconception'
Just did some searching on the internet and found a site called DragWorldUSA.com. They have a bunch of old publications listed. Not sure if the site is even up and running.
Anyways, I think Volumn #12 -- No. 4 might be July 8, 1966. I could be wrong. The list that the guy has indicates Drag News had a really bazaar numbering system.
The other 2 Chrysler cars went out on the 17th.
