Alternator pully size comparison

Water pump pully size comparison
The install was a breeze as expected but I did run into a very slight interference problem with the PS pulley.
As you can see here the over sized pulley just slightly rubbed the bushing on the bracket.
I took a little material off of the sleeve and it's all good now.
When installing the Alt pulley you need to ditch the 2 spacers to get proper alignment.
The stock pulley was a 2 piece stamped plate design and needed the spacers for offset and to
keep the plates rigid. With the VAC being 1 piece they aren't needed.
Do not use these pieces
