Body Identification of random body fasteners.

In the photo below, I have five square nuts welded to the bottom of my tub. The through hole (near the wire harness) has 3 locations, one on each side and one in the middle. They are too far back for the rear seat attachment, any ideas what they might be for? Next, what's the blind hole that is above and to the right of the body mount? It is mirrored on the other side. The threads are gone so I need to know if they need replacement.

Thanks.

I spent some time yesterday removing a rusted out toe support and got a closer look at the rear cargo supports. Apparently, Jeep used the same support in both areas and I missed the fact that there is a third nut under a piece of sheet metal. Still don't know why the furthest rear nuts have a through hole into the cargo area.
