LBJ and George Wallace documentary?

I have been asked to locate a short documentary about the conversation between LBJ and George Wallace that took place on March 13, 1965 regarding the civil rights movement and the Selma to Montgomery marches. While there is a massive amount of documentation of the events, I can’t seem to find this exact video, which is supposed to be focused on LBJ’s skill at persuasion. I’m thinking it might be a segment of a larger documentary, such as the one on George Wallace that was shown on PBS’s American Experience.

Does anyone have any ideas?

I don’t know if it will help, but there’s a dramatized version of the conversation between Johnson and Wallace in the 2002 film Path to War, acted by Michael Gambon and Gary Sinise.

Thanks. That scene is great – and the next clip that popped up on Youtube was the story of that moment from the LBJ documentary on American Experience, which is almost exactly what I was looking for.
