[LargeFormat] Linhof Universal viewfinders

[largeformat@f32.net]

I want to put a viewfinder on my Wista VX, and from their descriptions the
Linhof universal finders look promising. 

However I was wondering if they have an adjustment to switch between
portrait and lanscape mode (to go with a rotating back)?

I understand they use interchangeable masks to set the field of view, are
these readily available (or alternatively easy to make or have made)?
