I have 2 of these toolboxes available which are GM Accessory toolboxes. They have a sliding tray, gas struts to hold the top open and are obviously polished aluminium diamond plate so they look good. They both come with a Chevy Bowtie or GMC emblem that can be added depending on which you drive if any. They should fit almost any size truck… 69 inches on top (the part that sits on top of the bed) and 62 inches long in the well of the box.
$380 including tax for either one.
