Need help with part I.D.

[DeadLifter]

Does anybody know where a good place is to get a lower grille on an 08 GT? And what is the black plastic cover that bolts on under the front bumber and goes back about two feet ( I think it's meant for keeping dirt out of engine compartment), and where can I get a new one.
Thanks

Try CJ Pony Parts. I know they carry the splash shields
