I just installed one on a W124. Bought it from a dealer for $65, but if you want to save dollars you can order them online at www.mercedesautoparts.com,
which lists them by body number and takes custom orders. There By the way, I discovered too late (I'm a newbie) that the W124's have releases on the hood stops which allow the hood to be raised to vertical. Good idea for gluing on the pad. Good luck.
