Yeah, plexiglass is RIDICULOUSLY expensive, I believe the thinnest sheet (I don't remember the dimensions) at The Home Depot is around $20 if I remember correctly, and it will barely make 2 windows. They also sell glass, which is cheaper, but I bet after a day of 2x4in' (4x4ing in a 2wd) those things would probably find themselves broken. The truck this came off was an 80's d50 with a 318, and a custom paint job that said 318 on the side, and the guy wanted to take the tires and wheels off and take it to the scrap yard. Anyway I got the shell for $50, and it was only 2 or 3 miles away. Now I am looking for a short bed truck bed trailer to semi permanently attach the shell to, so when I go camping I can ditch my camper at the site and go exploring without someone taking my spot. The cheapest one I found is a 80's Toyota sr5 for $200
