Yes, the VW 068 903 803D part is the right version for the Vanagon 90
amp Bosch alternator. It is also used by most alternators on 85-92 VW
cars with 90 amp alternators. Extremely common. No, you can't expect to
find that VW number on the regulator itself since most are long ago
replaced with generic Bosch or knockoff regulators.
