Fastback Barracuda trunk info

yep. its a one piece piano hinge. it has 4 holes per side. when you order the carpet kits, they send you the sides and bottom. under the flat portion of the rear cargo area, there is a thin board( i used masonite) to cover the strengthening ribs in the metal pan. the carpet then goes over this to make a smooth floor.

here is a what mine looks like.
