Cutlass Supreme - which power steering fluid

Which is the recommended power steering fluid for a Cutlass Supreme 95 3.1L?
In my owner book, it's says: GM Hydraulic Power Steering Fluid (no: 1052884).

I don't want to go to GM just for that.
I'm looking for something equivalent easy to find at gas station or auto parts store. Such Mercon 1/5, Dexron 3...

Any store bought p/s fluid will do it, not trans fluid.
