Water pump pulley

Currently putting a Vintage Air kit on my car. I have a single groove water pump pulley. Do I need to go to a double groove? If so, does anyone have one? The car also has power steering.

Depends on the kit, does it need a double groove pulley?

 

[Z06killinSBF]

I dunno. Kinda looks like it could use one. Directions dont specify

The P/S, A/C cars used three belts total with a two groove W/P pulley and a 3 groove crank pulley.

Hmm so I'm gonna have to get a 2 groove pump pulley then huh? I had to get the 3 groove crank already.

Well, does anyone have a 2 groove pump pulley?
