Here are the fogs, and I found a guy with a few sets for sale.

Dave> I know you're gonna chime in here. You were right, the bumper is indeed an "IS" bumper. The "ES" bumper (like the picture below) does not have the two extra holes in the bottom middle. Crazy! Something else, if you google E30 "is" I have not seen a single picture of this bumper on any car other than the above. Very unique indeed.
