Crazy day. Here's what I found. All rods are in 3 sections.
LE: 12mm OD, 8.75mm ID
Upper 33.25" / Middle 33.25" / Lower 33.25"
"Bend" in spreader fitting 29" from front of rod section
Spine and Spreader: 12mm OD, 5.9mm ID
Upper 26" / Middle 26" / Lower 26"
There's a plug in the end of each assembled LE, spine & spreader with a small hole. Bungi goes through with a simple knot outside the plug.
A couple of pics to more easily show the ferrule locations, connections and "fitting" placement...
As a point of comparison, my ITW Sweet 16 uses fg rods - 13.78mm OD, 11.95mm ID for LEs and spine; 18.82mm OD, 16.15mm ID for spreader - 2 sections per assembled rod.
Hope that helps.
