I did have one of those RCA radios, but Mine was a C8-16 which has a very similar cabinet.
         Although mine did not have all the challenges you have with the rotted wire.
 you do have a bit of work to do ..but the radios do sound very nice and look good.
              I agree that you do have a fair bit of room under the chassis.
      The wood on my cabinet did come out very good and I do see some similarities in both cabinets,
and the dial is the same.
  The little knob with the world on it just adds to the look of the radio good luck in your restoration.
Here are a couple of photos of mine.
