Oh geez... JUST tossed mine out. The length is VERY close to the actual wing which is 65" so the box couldn't have been much more than 67" with the small foam on the ends of the wing. There really wasn't much protection on the tips!
I would guess at 14"-15" on the box width as it too was close to the wing size and the root of the wing is about 13".
Height - total guess at between 10"-12"
I'm guessing maybe you're looking at shipping girth, and if that's the case I hope someone can provide exact measurements. Mine came from Tower packed in another outside box as well so that added 3/8" or so on each side.
Just completed mine:
