Hmm. My wife managed to destroy mine on the 300te Estate (Car wash). I hunted e-bay etc found some but they were just silly money. I ended up going with a universal one from e-bay and using the Hirshmann grommet. Although the universal came with grommetts that look perfectly good to me. For £14 I figured it was worth it. I still have the original Hirshmann but it has a busted pole and no guarantee that if you replace the pole it will still work (waterlogged).
