which manual tranny fluid should I use for my 97 legacy?

I checked my dipstick for the manual tranny and it's low. The guy at napa sold me some 75w90 gear oil but after checking a few different places I think it might take Dextron III like my truck. Which do I use?

Pick up some Subaru Extra-S fluid if you can...

My car's have 80-90 in them.
