For the top part I am currently thinking of using a heavy transparent shower curtain liner, stretched over it and held down by retainers made of flat bar. I bought one for $6 at Walmart, and they seem to be at least as transparent as a convertible top window. Shoud be good for starters. If it works out well and if we get back on 40 hours at work, I would probably try lexan. The flat bar I can get for free from the scrap pile at work. I want to keep this as economical as possible. For the sides, I am thinking of either coroplast, aluminum sheet (I have a roll I picked up from a garbage pile once), or steel sheet from a dryer skin (which I might just do since I can weld it to the frame and add to the rigidity).
I have this idea for the rear. Same as I did for a trailer I made a long time ago. The lights are 4 1/2" round trailer/truck lights. The license bezel with backup lights is from a Celebrity (or other a-body) wagon.
