Whoa, there are extra ones? Like enough to relocate the seat?

Do you mean gaps at the edges? Or voids underneath (above) the headliner?

Brilliant! You mention cutting the two back panels, I presume for width. Did you cut for length too? Or are your front seats far enough forward? I can't quite tell from the block of leftover foam riding shotgun... Also, did you need to put any sort of plank or support on the folded seats? Or just threw the mattress down as-is?

On my van, there were threaded holes everywhere. Some I never found the right size, but there were at least three on each wall, around what would be the windows in your wagon, that fit the same M10x1.5 thread that the cargo tiedowns go into. Yours unfortunately are behind the plastic panels, and I think two of them are where the seatbelts mount. A bed covered two of my tiedowns, so I mounted those to the wall. Grabbed a couple extra bolts from Home Depot to hold more.

Front seat on whichever side the box is installed can slide all the way to the rear. At factory seat height, like on the passenger side shown here, seatback can recline about 3-4 notches. My driver seat is raised 2” on suspension lift blocks, so it reclines even further.

Front two compartments are open from both sides, so longer items will fit. Front two compartments will hold 2x standard milk crates each, and the outboard crates protrude few inches for easy access, but are held in place by the sliding doors. 

Milk crates or Muscle Rack / Insta Crates fit underneath. 5 compartments, usually I have 3 totes and 4 milk crates.

View from front and rear quarters. It’s a mirror image; the box is reversible to it’ll fit on either side. Two sets of tiedown holes drilled.

Some details and photos on the bed platform, which perhaps will help someone trying to visualize their own.

SOLD Have to sell my van (moving abroad) and since it might end up at CarMax, I’m offering the bed for sale separately. Built from 22/32 5-layer maple plywood, it is 75”x25” and about 14” tall. Space underneath for milk crates or folding bins. All joints are Kreg pocket screwed and glued. Visible portions painted black, top covered in indoor/outdoor carpet. Handed cut in the ends to haul in and out, or reverse from one side of the van to the other. Holes drilled to use the factory tiedown holes, and I’ll provide M10 15mm hex head hardware to anchor. Available in Washington, DC immediately. You’ll need to pick up, though I drive up and down US 29 in Maryland and could meet along there.
