Just an update

so I found this pulley on amazon:

2 groove alternator pulley

and it worked like a charm. everything lines up just right and spins as quiet as can be. single groove pulley came off and the 2 groove went right on with no trouble at all. love it when that happens. will try to get a pic of the new setup.
