I have a 98' Audi A4 2.8 Quattro V6 (B5)
Not sure if it is the Avant.

I am looking to buy a Front Bumper Grille piece that is located on the passenger side, the lower grille piece that covers the A/C Radiator Lines (Hoses)

and looking for a Belly Pan for the front.
I have two metal straps just hanging under the car and each have a single hole through them. My guess is that is for the belly pan, or engine cover, not sure what it is called, but I am missing one and would like to purchase one if anyone has one.
Thanks...

Here is pictures of the car.
