Location for the 68-70 B-Body Deck Filler Support

Where does the 68-70 B-Body Deck Filler Support go?
Pictures would be great!
I am trying to figure out if I need this, and I can't find anything that looks like it.
Also I noticed in AMD's 2012 catalog it says "2 pieces per car"

They go just behind the back of the rear seat to support the package shelf. They form a V coming up from the center of the floorboard.

The only thing that I can find that looks like the picture is on each side of the plenum. Which is underneath the deck filler.
So maybe if you order the plenum you need two of these, one for each side?

Or are these the ones under Dutchman panel, or deck area behind rear glass , there's one either side of the plenum to surport that panel

That's what I think!

I see, the supports I mention have double ribbing......
