1977 Vintage KENNER STAR WARS Death Star SPACE STATION withMonster Foam Compactor

I believe there's a small, tan piece missing behind the trash compactor (as I've seen in other online pictures) - inside the Death Star and maybe? Please ask questions as needed. Includes the monster (in excellent shape), original foam in two colors, trash compactor, and two cardboard front/face inserts slightly worn from use.
