If you are talking about the rubber washers that go between the upper W/S mounts, and the 'special steel washer', they detoriate very quickly... I went to the hardware store, and went through all the rubber washers and 'O' rings in the place, and didn't find ones the correct size... Ended up buying rubber washers, that had smaller holes than the OEM, and used a hand held 'paper punch' to make the holes large enough for the mounting bolt, and steel washer collar to pass through...
Gotta get creative

If ya don't want to pay the price for the Honda OEM's.
