I recently purchased a Super Graphic, but it did not come with the ground glass assembly. I thought I could use the back from my Crown Graphic, but the Graflokk rails seem to get in the way of the hooks on the back. Does anyone know where I can find a back for the Super Graphic?
I might be able to modify a Crown Graphic back, but I would like to keep my Crown Graphic whole. Are there any sources for inexpensive Crown Graphic backs?

Thanks!

Inexpensive is a relative term when it comes to crown or super backs, often times, I have seen them sell for just as much as the camera body themselves.
