I need a small trim piece for my Rallye Golf
 

If anybody can help me out with locating a rear passenger side one of these trim pieces, I would appreciate it! This is the piece that bridges the gap between bumper cover and wheel arch in the rear. Thanks-Tom

Almost impossible to find , however you could go to the breakersyard and see for a passat 35I
It seems they have also almost the same trim .
With a little work it should fitt.
