As far as I can tell all three of these Dittel radios use the same mounting tray, connector type, connector location and wiring layout so I should be able to slip a 60 or 60M right into the mounting tray I have for the FSG-50 in my glider. Can anyone with experience confirm this for me?

I finally had a problem with the FSG-50 in my ship and before I go through the cost and hassle of replacing it with a new radio I'm planning to see if I can either get it serviced or possibly replace it with a working, used 50/60/60M.
