this one about 2 months ago. I want to upgrade to dual t145 golf cart, so I needed a box. I didn't like the plastic ones, and the aluminum is just to expensive. so I made this from an old toolbox I salvaged. I made up a brake to bend the aluminum, bent up the box then gave a local weld shop $35 bucks to weld it up. With the stainless snaps, aluminum vents, vinyl tubing for edging, and plywood I think I have less than $50 into it.
