Plastic underbody

I'm looking to see if anyone knows where I can get a new plastic underbody for under the engine. I have my 98 A4 lowered and I caught the front on a parking block. When I backed off, it pulled it out from the front bumper. It finally fell on the ground while I was going down the highway and now it's trashed. Do I need it? Or does anyone know of a wrecked one that I get it cheep? Thanks

where are u from

Indiana
