Euro Reef help needed

[cdub]

I took apart my sedra 5000 today to clean it and i lost one of the small black washers that go on the ceramic shaft. does anyone know what size these are or where i can get a replacement?

i checked online at euro reef and they are only 50 cents, but i don't want to pay $9 to ship them.
