I found limited availability for my '01 Sport grille.... so I made a set of winter front inserts out of aluminum sheet. After running them for a while, I noticed that the tubular grille support was being forced back into the fins of the A/C condenser and was rubbing on them. So, I ended up taking the inserts off and straightening the fins back out. I guess at highway speeds, the inserts were catching enough air to deflect the grille back into the condeser. I don't run the inserts anymore.....

 

There called bumper panel, you can get them with or without holes for fog lights, the part number for the panels w/ fog lights is 88654.
