Thanks, Capote. I've inquired about the box at the usaspareparts.com website.
I'm usually pretty good at finding obscure parts on here, i'll keep looking. Hopefully I can find one.Thanks Capote and Mooseman. To clarify, I'm only looking for the Envoy XUV accessory storage box, #12498502. It looks like a plastic tool box and bolts to the side of the cargo area in the XUV. I inquired twice at the usaspareparts.com website but never got a response back from them.
