As far as install goes... Its really just those 6 push in upholstery (?) fasteners. They compress to go through the holes in the middle of the cardboard and then through slots in the vertical braces of the seat back. Then expand again once you release them and the expansion stops them from moving back out and keeps the cardboard fairly tight.
Does the repop piece not have any pre-punched holes? Im not sure where you would get the fasteners from. I was able to reuse my originals.
