Organizing a Nitro Z19

I am trying to get organized...no really! I am, but it is difficult when you're OCD. I'm having a heck of a time finding tackle storage boxes that fit my Nitro 19. They are either too wide, too short, too long, etc. Every organizer I've tried fits so loosely that they will bounce around in the compartment. Anyone else have this problem and found a solution? I suspect that I will simply have to live with the boxes not fitting snugly.
