Humm, the part in the article about Boeing never having outsourced wings or fuselage before rang a bell. I thought I recalled that Northrop built a really big chunk of the 747 fuselage.
Here is how Vought Hawthorne represents their 747 contribution:
"Hawthorne employees have produced the Boeing 747 fuselage since the program began in 1968. This fuselage section is 154 feet long. Each shipset has 28 major panels, delivered to Boeing in 13 custom, oversized railcars."

It appears that the Business Week article improved that point a little. One wonders how much of the rest they may have similarly dressed up.
