Hi guys, sorry but Booster Seal 001 430 0708S is a replacement for ATE Booster Seal 03.7718-5028.1, and only fits certain 1998-2018 Mercedes and Volvo models. It won't fit a 300D booster.

Well darn! Thanks for letting me know and saving me the trouble!

Any chance URO has any plans to make one? The development costs can't be too outlandish, and I know there is a large community that would love to have one.
