I am selling the fiberglass cap from my 05 GMC. It is for an 8 foot bed. I think it was originally for a dodge truck, that is what the guy I got it from said. It sits pretty good on my sierra. It comes with the clamps and I think two sets of keys. Each window (3 of them, 2 side 1 rear) has 2 locks each. The side windows are matching keys and the rear is different. It has a cargo light and third brake light. It is white and has a few scrathes on it but overall it is in excellent shape. I will get pics Sunday and post them up. When I was shopping for one The same size/type were selling for $1K-$2K. Starting price of $500 OBO. I am open to trades as well. P.M. with any trades or offers. Thanks, Sean
