I just bought a 2004 A4 Cabriolet that was in great shape but minus a belly pan/engine splash shield. I found an OE replacement that was guaranteed to fit and supposedly with mounting hardware, but alas, it came with none. The dealer wants $85.00 for the various lock-screws, washers, and nut/clips. I can't find anything else online. Am I doomed to buy this hardware from a dealer?

 

I'm also missing some of the lock screws. WalMart
uses Zip-Ties to hold the splash shield in place.
