Fuse panel access 2300 SC

[Jhunter936]

Hi, new owners of a 1997 2300SC. Just catching up on deferred maintenance. Is there a way to remove the entire wall in the head to access the fuse block? I got the 2 smaller panels off. The main wall I found 3 screws and one side is now loose but the starboard side is set in place. Am I missing more screws that I cant see?
