Looking for a 3.5L intake .. only need the top half not the plenum .

For my 1971 280SE 3.5. Mine has a cracked casting at the rear runner pair (PO got over-zealous removing the rocker cover and chipped the manifold). Need a serviceable top half only - my plenum is fine.
Photos above are reference of what I'm chasing - this is the M116 3.5L upper intake. Bottom plenum I don't need.
