From the TV Factbook II 1967 edition.
While this section shows what channels were carried, it does not show what the channel numbers were, so I'll list them in the same order as the Factbook.
KDIX Dickinson, ND (CBS/ABC)
KMOT Minot, ND (NBC/ABC)
KFME Fargo, ND (PBS)
WDAY Fargo, ND (NBC)
KTHI Fargo, ND (ABC)
KFYR Bismarck, ND (NBC/ABC)
KXMB Bismarck, ND (CBS/ABC)
+ FM
It did not specify how many FMs they carried. Bismarck and Minot each had an FM station broadcasting by 1967, so it could be either or both.
