I am trying to find a US source for parts for Goiot "Crystal" hatches. These were installed on our Jeanneau SO 45.2 and are fine..but.. the "friction rings" have pretty much disintegrated and need replaced. The Goiot web site lists the part number as 95346, but they don't sell to the public. Is anyone aware of a US source for these parts? (or an alternative replacement) Any help would be appreciated.
