What\'s this 8\' box worth? My friend wants me to sell him an 8' fullsize pickup box off an '82 Chevy that I have. With an exception of two very small surface rust spots, it's near perfect. The only thing it's missing is the tailgate. No dents, dings, or bondo. It has the fuel doors, and is for dual tanks. I want to give him a good deal, but I dont want to give it away either. Whats fair market value for it?
