So I bought a huge tool box I am keeping in the back of the explorer right now. It takes up about 60% of the cargo room, but I really don't use the rear half anyways. So the picture below is how we have our tool boxes at work. It makes it really easy to see if you have a tool missing, and holds them tight. I need it so my tools don't bounce around as I drive around and obviously so I don't forget and lose tools on a test drive (have done this before lol). What I need is help finding the foam I can cut out like this. Tried and arts and crafts store, but the foam was more like Styrofoam and would not reform after you pressed on it.
