Hi Everybody, I am missing the centre hinge on my britax weathershield roof sunvisor. A real long shot . . . but does anybody have a spare for sale? Is it the same as the 2 outer hinges, or does it have a locking mechanism on it? Maybe somebody who has one can send me a pic so I can see what I am searching for? Also need a new cover - who can recommend a good supplier? Thanks in advance.
