Being on this stage coach that is held up by outlaws will be mentioned by Hayes two weeks later in The Root of It All (1971).
Even the plot point of the outlaws later realizing they were Heyes and Curry will happen in the later story, although what happens after that will be completely different. The plot point of being held hostage in another way station will be reused in Shootout at Diablo Station (1971).
Sallie Shockley plays Randolph Mantooth's wife. They were both in Emergency! and Adam-12.
Even though seven outlaws attack the stage station a shot of the gang before they rob the stage shows nine mounted men. This is because the shot is taken from episode 1x4 'Wrong Train to Brimstone'.
The director, Richard Benedict, is the father of Nick Benedict, who plays the outlaw Phil.
The building used as the way station is the reused home for the Boone family from Daniel Boone (1964).
