the 050789 PN: 0044300901 has an ATE master cylinder on pelican and not for the opposite. However, for the brake boosters, the Genuine mercedes part is PN: 002-430-68-30-64 and there is an ATE listed with the same number but there is ALSO an ATE with PN: 002-430-68-30 and the note: 9" diameter with threaded vacuum fitting.

When I get home ill check my booster PN
