[C320-list] Pedestal and stern rail diameters?

[onedrop7 at yahoo.com]

I became the owner of a '95 C320 in October and have a really basic question:

What is the diameter of the pedestal rail (Edson EB-204-3) and the stern rail? (cockpit photo: http://kevjot.com/boat/cat320c.jpg )

I'm looking into RAM mounts and it would sure save me time to not have to drive an hour to the boat just to measure this.

Thanks!
