I'm still working on perfecting my shelf. But what I did was when i pulled off the trunk carpeting from the rear tire wells, i noticed that there were holes where the clips used to be that held the carpet in place. I cut wood panels, and bolted them in place. I used those wood panels, and put the shelves in place. I've got pictures, but i just didn't get the chance to develop them yet. Hope this can help you out.
