5.0 Great Cover, Looks Great

I bought this at the local 4Wheel Parts store. Great product looks good. It really helps having a local 4WP store in town. The guys that work there are very professional. Very nice store. I will shop there again. If you have a store like this in your town. Your a lucky guy.
