thx for the hall sender audi 4000 X-ref vanagon you guys are invaluable :)

Now I need some more x-refs on alternators
there is a ebay seller in van bc that just found out about a local
start/alternator rebuild shop that went outa  biz
hes blowing out some 200+ rebuilt alternators for 39.95
he listed these audi part numbers
 Ref #  A6711, 14396  026 903 015B
are these the same as the bosch al33x
and I assume since gowesty  sells al33x for 83-91 that
all i need you guys to confirm is that this is just AL33X

ps. instead of bugging you guys is there some internet x-ref
for all part numbers somewhere or x-ref specfic to the vanagons ?
