3 speed transmission oil?

Hey Guys,

I'm going to drain the tranny fluid in my 59 which has a 3 speed manual. What gear oil should I use to fill it with? Brand or picture would be great to include.
Can i use standard rear end gear oil in the tranny?

Wear an old shirt you don't mind throwing away. Unless you have a good pump can setup it seems that you always get some gear oil down your arm and on your shirt.

Regular 80/90 gear oil from the parts house should be what you want.
