You'd have to find one used, it fills the space pretty well but wasn't too popular. It is fully enclosed.

Thats not like mine. Mine is flush on top, has fabric covering it, and no locks. Also mine looks a little bigger. I'll take some pics tomorrow.
Mine screws to the tub on the sides. The lid on top has two sliding lock bolts inside. I guess so you can load from top and via tailgate. Idk. Never used the top. I just access it via the tailgate.
Sorry to hear they are not made. Glad my PO put it in. Its a very functional trunk. In wasted area really.
