W&N has part # 63.21.1.811.001 ( second image below) listed for the E9 which I got from doing a search here. But owning an E24, it uses that white spaghetti gasket that I belive may have been original to the E9 also? I may be wrong since my chrome lens holders have no gasket at all. I am set on the actual plastic housing gasket. Can anyone confirm the picture below on the left was what was original. The image is also from W&N but for the e24 which should be long enough to fit the E9.
