I have found some additional pulleys that can be used in this application.
Powermaster makes OD pulleys that Jeg's now carries.
The one I went with for my newly rebuilt Police Alternator is:
713-115 - 49mm, Natural Finish OD Serpentine Pulley $7.99 @ Jegs
They also offer these:
713-114 - 54mm, Chrome Finish OD Serpentine Pulley $22.99
713-105 - 49mm, Chrome Finish OD Serpentine Pulley $19.99
713-104 - 54mm, Natural Finish OD Serpentine Pulley $8.99
713-175 - 46mm, Natural Finish OD Serpentine Pulley $21.99
