Keyway Pulley Puller Tool

[chevyc20gal]

Hi all!

Thank you in advance. I'm stuck. My power steering pump went bad. I am looking to buy the right tool for a keyway power steering pump pulley for my 1971 Chevy C20 350. I previously used a generic pulley puller but I could not get my pulley back on with the generic tool. The manual calls for special tools. I do not have the manual in front of me, but I can post a pic of the tool specs later when I get home.

I've attached a pic of the pulley.
