I have a pair of B5 perches for sale. I fit these last January (2013) to the wifes B6 to lower it a bit extra up front, but she hated how low it was so i've had to raise it. They've only covered approximately 6k miles, we don't do a lot of miles in her car. I've run them under the tap to clean up the dirt, and they have cleaned up rather well. Hardly any signs of wear on them.
These are part number; 8D0 412 103B
Looking for £25 posted for the pair to (UK only) as these sell for near enough £50 now.
Here's a couple of pics.
