I recently picked up a 2008 sedan to replace a too-crappy 3rd gen wagon for daily duties. The exhaust manifold/catalytic converter were very recently replaced, but it only seems to have a partial splash shield setup. I have left and right side pieces that cover either side of the engine and form the usual vertical guard areas that cover the area forward of the wheels inside of the sides of the bumper, but the center area is completely open in a way that looks like it is missing a third piece. All of the splash guards I've looked up are one piece (like 56410AG15A) and the listings specifically exclude the 2008 model year from the fitment information (2005, 2006, 2007, 2009). Does anyone know what part I need?
