Swing shower wall in a 1998 symphony

I Hi does anybody know where I could find a complete swing shower wall from a 1998 symphony please ours is missing?

Do you mean the fold out partition that creates a privacy screen? Calling it a swing wall conjures up the washroom of late Nuevos, Broadway's etc . 
You're unlikely to find one to buy. You'd be better asking if anyone near you could help you get dimensions and shape to get one made, they are only made of plywood.
