How to remove PS box

Made a little bit more progress this week. I got the box out, degreased it with OzzyJuice (really cool stuff), and separated the pitman arm after marking the location. Opened the box up and replaced the input shaft seal and the big o-ring there.

Still to do:

1) Figure out how to get the pitman arm seal out so as to replace it.

2) The steering shaft kit came with a big o-ring, the seal, and a tiny o-ring - anyone know what the tiny o-ring is for?

3) Replace the pitman arm bushing, which was either trashed previously or as a result of my efforts to separate the center link. Anyone know where to get a replacement bushing? NAPA didn't have one and without buying a new pitman arm, not sure where to get it.

3) Paint

4) Install
