We paused the credits three times already, we both thought the youn girl looked familiar but as you said Lee Majors did not get a a credit neither did she.
According to the Imdb, the uncredited actress was Patricia Crest (aka Patricia Krest). Very little about her on that site. Just a few credits and nothing after Strait-Jacket.
Not a familiar name or face to me.
