Helm seat Loose
The top section of the helm seat (brown) on my 330 has come loose from the next section (white). It seems to be attached to the white section by a metal bar at either end (directly below thumb). The bar seems firmly attached to the brown section, but then the brown section can slide up and down on the white. Only the left side (as viewed in the photo) is loose. I can see no way to tighten it. I tried feeling all around the lower sections for any kind of fastener to disassemble the section and then tighten the loose part somehow, but came up with nothing.
Somebody put this together, so I figure there must be a way to fix it. Anybody have any ideas?
