Alternator Bearing Part No. trouble

[Per Lindgren]

What I found in the EPC did not make me any smarter, but from looking at the
1992 A100 it looks as though the bearing you need is 051 903 221B. It's funny
though, the alternator 026 903 017 BX is listed for both 1988 and 1992 (and
probably all in between) but the bearing is not the same.
