This is a replacement for original flat oval plate with a round pin that is offset in the Y-pipe. Does not fit the older round Y-pipe.
For 1982 to 1996 engines, there are some 1996 and 1997 models that apply. . Fits oval 4" Y-pipes with round pin holes. If you have two rectangular holes for the grommets you need the A1 water shutters. If your Y-pipe changes size a few inches bellow the shutter you have a one piece manifold V6 Y-pipe and need shutter A2.
