'95 E420

shift lever is sloppy as all get out and it makes what I would describe as a metal-on-metal friction sound. and just recently it started to cause problems with not engaging gears. So without even looking I know the lever bushing are shot...if they're even there anymore...but anyways my question is how many different types of bushing's are there? Fastlane shows these two little guys, are there any others? I thought I read about upper bushings or something.
