What vehicle is GM P/N 19132453 for?

[Hmmm2]

I don't have the answer to your question regarding what vehicle that cargo cover is meant for, but it looks like the one I have in my H3. I got mine when I bought the H3. You probably already know this, but it goes corner to corner in the cargo area .. a top cover. It's VERY rigid and extremely difficult to hook the final hook. The salesman couldn't do it .. so I did. () It's taute on top once hooked, like a trampoline.
