Just an observation here to add to the confusion. Note for example the 1005 824 071 number is on the nose housing. Alfa and Bosch have typically used the number on the field coil housing as the starter assembly number. The Series 3 Spider starter I have here shows 1 005 231 071 on the nose housing but the complete starter is listed in the Alfa parts book as 0 001 108 024, the same number that's on the coil housing. It would seem that the 1005 824 071 is the part number for the nose housing only.
