Sanford Arms (1977 TV Show)

So,I found out about this show named Sanford Arms. It was a spin-off of the popular 70’s show Sanford and Son. This show was short lived. Lasting 1 month, And 8 episodes. The show lasted from September 16 to October 14, 1977. But the thing is, The last 4 episodes were never found. The episodes are Episode 5 “The TV Show”, Episode 6 “Young Love”, Episode 7 “The Wedding Reciption”, And Episode 8 “The Ernie Williams Memorial Golf Course”. Anyone is welcome to help me with the search. (Update! I just found out that Episodes 1, 2, And 3 are also lost! The only episode that was found is Episode 4!)
