Bad picture because of the the rain and the f'd up airdam, but you get the idea...
Its the alternate 240z grill.
I chopped it to make it fit with the air dam, otherwise its about a foot long so it covers a 240z behind the bumper and fills the gap. Had to fab up a bunch of crap to make it mount on a 280, but the early 240 it mounts right up to the holes.
