Tie-rod rigging source

A friend lost his rigging on his Hunter 380. Replacement mast and boom are easy to find but we need a source to manufacture the tie rods that connect the D1s to the hull. These are roughly 0.56 diameter 3 ft long with threads on one end and a plate/tang welded on the other end. Hunter did provide him with a drawing.

He and the boat are in Alabama (rig is at the bottom of the Gulf), so looking for a source in the states. I would guess that any decent machine shop could make these, but no harm in asking if anyone has some suggested sources?
