Generation IV External Engine - Pulley

I have a 6.0 lq9. I'm tryn to run f body accessories. I'm having a hard time find the power steering pulley. Does any one if I can use a different Pulley?

You can order a pulley from Turn One.

All the truck and f body PS pumps use the same shaft diameter, along with pretty much every GM since the 80s. So they can interchange. Vettes are different.
You can order pretty much any of them. Check out Rock Autos website.

Any one else?
