I've looked around and I'm either not using the right search criteria or it's not out there. I found these over at Expedition Exchange and I have no idea how to mount these in the cargo area. I pulled up the corner of the carpet and padding, but didn't see any obvious areas to secure these to the floor.

M8 rivnuts? Hide and go seek as I drop the bolt down from above to secure the nut from below? Stock mounting points that I didn't see?

Thanks!
