From the info I have it looks like the staters are the same part number. On cars up to eng.# 116 965 12 054964 you will also need a different centering plate part# 116 151 03 45 to go with the new starter. If I remember correctly the later starters are smaller and use an aluminum centering plate. The early starters were much larger and used steel shims but no centering plate. The part number I came up with on the starter is 004 151 78 01.
It's possible that this number has changed again,My parts info is several years old.
I hope this helps, Robert.
