I have a '95 LS and I have the manual right in front of me. Hmmm.. Lets see....

From the Fluid Capacities page:

Power Steering: Capacity. 1.1 Quarts. Type: Automatic transmission fluid "Dexron II"

And for the record;

Automatic Transmission: Capacity: 7.9 Quarts. Type: "Diamond ATF SP", "ATF Dexron II" or equivalent.

Dexron II is no longer availible. It has been replaced with Dexron III and then Dexron IIIh and the latest I believe is Dexron IV. However, most stores just carry Dexron III. This is kind of a sensitive subject around here, but per the Dexron specs, Dexron III is backward compatible with all previous versions of Dexron fluid. I think you can use Dexron III for the power steering fluid or the ATF for '95 and earlier vehicles.
