A friend of mine installed a front storage locker between the firewall and the subpanel. This is where he keeps a quart of oil, rags, and windshield cleaning supplies. Very handy and I decided to duplicate. I ran a couple of angle braces and made the sides and floor from 0.025" sheeting. The door is made from carbon fiber layups using the top skin as a mold form. I also made carbon fiber backers as well.
