You can get the part #s at a dealership. I'm sure they can get the parts for you, or you might try an online source.

This brings up a good point. I find it very annoying that only the stealer has access to updated parts diagrams and catalogs. Even John Deere has an online parts system where you can get part #s, diagrams, dimensions, etc. You can even order online and have things shipped to your home, work, or the local dealership. When will MB catch on to this?
