Spacers for 993 fan hub

[ahendy]

On a 993 engine with a standard dual pulley 993 fan hub, should I be utilizing all three shaft spacers that come with the alternator? Inclusive of the larger base spacer, presumably. Or a different arrangement? 

All three spacers plus base spacer gets the pulley location to look aligned to my eyes but difficult to tell for sure.

Sorry, to add detail... this is for the 175a alternator!

The spacer provided with the alternator brings the alignment to the same place as the standard alternator.    From there on, use the Porsche spacers.  RS has a different arrangement to the regular cars.
