Ah crap I should have told you to just remove the entire shift housing. There's no bushings inside the shift tower itself. The shift lever simply pivots on steel pins and a metal box inside the tower, so there's no bushings to replace in there. All you can do inside is check for wear on the box itself or it's pivot pins, or pivot shaft for the shift lever.

Don't be intimidated by the shift mechanism. It's actually not that complex, and really rather simplistic in my opinion.

As far as the other bushings go, they typically don't swell because of the type of plastic they are. Instead they crumble to pieces when they get hard & dry. Do a search on the forums here and you'll find TONS of posts about shifter repairs and shifter upgrades. Should be plenty of information to help you understand where the problems are and how to get it all back together.
