Looking from the rear with the wheel off, look at the right side of the rear drive. You'll see the cushions. Not a bad idea to inspect them but as MOB said there shouldn't be any reason to replace them this soon.
I don't think there is anything wrong with them, but I have a new set; so I figured I'd get them in.
I'm tempted to start selling the accessories separately!
If I were you, I'd sell your extra parts and accessories separately if you can. You'll get more back than selling them with the bike. Up to you, though.
