my two door Jeep Wrangler JK does not have the back seat and I end up throwing all sorts of loose items including tools in the rear compartment. In the event of a roll over the items will fly everywhere. To remedy this I started building a bank of drawers that attach to the stock seat mounts. First I built a simple mild steel bracket. The bracket will capture a piece of 80/20 extruded aluminum that will act as the foundation of the box. I followed the contour of the inner Jeep fender with a flexible drafting tool and transferred the shape to a piece of 3/4" plywood.
