Here is the finished result. So for $24 bucks, plus another $20 for (a future purchase of) steel tube, a body cart that cost only $44 bucks is not a bad way to go. I didn't get the cart under the cab yet. It was 9pm when I finished and decided to call it an evening. I'll post more progress when it is made. Green truck, recycled green steel beams, Phew, that's about as green as I care to get. Stay tuned as I patch the cab corners with parts from Classic Industries.
