toyo/omega 45 series camera rail question

I was wondering if there are compatibility issues between the rails/extensions for the Toyo/Omega 45E and G. I noticed the G rails have screws in the center.

The Toyo 45E is a "beginner" camera, so some features are missing. Extension rails, for example, cannot be used. You need the G series rail that has screws for adding extensions. It also came with a fixed bellows, and a non-revolving back.

I realized I actually should have put 45F. It has a rotating back and detachable bellows. I purchased a rail for a 45G, so that I could use the extensions.

Thanks,
Chris
