I'm hoping someone can help with a part number. I hit a tire tread on the freeway resulting in lots of broken plastic under the bumper and engine. The plastic tray under the engine is destroyed, along with part of the fender liners and bumper brackets.

The part number on the tray looks like 56440AG002 but when I type this in at subaruoem.com it does not recognize. Looking at the diagrams, it looks like I need 56410AG004 but this is labelled "Splash Shield STI".
