I actually own a flatbed 92 Ranger myself. After a wreck my grandfather and I built it out of wood, made it 8 inches longer than the long bed i had, it cost $175 bucks for us total, not including the mud flaps I'm not sure how much they were... as far as any problems with bed removal we had to grind off the bolts because they were rusted. I'm pretty sure it is legal in our state to drive without the bed if you have to, I just recommend getting the brake lights where they are visible and a set of mud flaps so you don't throw rocks at other cars, and take it a little slow since spinning tires is a lot easier without the weight. Anyway here is a few pics of my set up, of course going with metal would probably be more expensive, I'm not sure. Any other questions you have I would be glad to answer. Oh and I'm not sure of DIY sites or anything but I can give tips if you need it.
