He is talking about the tar paper baffles in front of the radiator. The ATR kit only replaces the sides and add 2 additional pieces on the bottoms. The large piece is the most critical.
Mine were looking ragged and I couldnt locate any. The dealer tried to look it up, but they didnt appear in any of the parts books. I decided to stroll out to Home Depot and see what they had. I went down the floor covering isle and came across the black, ribbed floor runner they sell by the foot on the large spools. I bought 3 feet of it. I took it home and traced my original onto it and cut it out with large scissors. I punched new holes for the push clips to go through. It turned out great! I also have the ATR baffle kit which is a nice addition, but a word of caution. None of the holes lined up. I have redrill most of them. The baffles are an enormous help in the summer trying to keep my car cool.
