Yes, the genuine AL33X is the only version I buy, in a Bosch box. I
suggest the Van-Cafe one as I'm not sure what games Ron is playing with
his part numbers. He sometimes uses other companies part numbers in ways
that are confusing if not deceptive. If he is offering Rebuilt By Bosch
parts but not telling the Official Bosch Rebuilt part number for the
item then we can't be sure of exactly what we are ordering. Bosch uses
their own specific numbers for their rebuilt items and AL33X is such a
number. It is perhaps the most universal of the VW 90 amp alternators of
the vintage covering our vans and many original Bosch longer part number
versions are all replaceable by the AL33X unit.

WBX Vanagons can also use an AL27X instead as the distinctions are very
minor at most. I wonder if the BD unit is one of those or if perhaps
they don't care to specify since it could allow them to ship either the
27X or 33X as available? Either will work about the same for WBX but for
my mixed fleet the 33X works with diesel tachs while the 27X often won't
so I have standardized on the 33X for all.
