Radiator tray? Parts identification help!

There was a brace that was bolted to that hole and goes down to the K frame. At some point it appears to have been ripped out. Hence why the hole is tore open. My car doesnt have one and I dont believe its a necessary piece.

Depending on how much work you are looking to do you can replace the entire section with something mentioned above or just hammer it back into place if you dont care how it looks.
