Thank you, but I no longer have the Pro body and I forgot to close the thread. Things went a little different route...I actually need a Pro S body to fit the things I have instead of the other way around. I have a lens, focus screen, revolving back, WLF and film holder for a Pro S, but no body. It turned out it was virtually impossible finding just the Pro back I needed and I ended up with all Pro S parts and no body. Crazy.
