these are also up on the ford performance site, under the media section.
i cant work out what is "new" about these other than the last 2 pages. They have been around for a while as they are the parts manuals for the road car.
Go to the link below to find a complete set of the original GT40 SAE papers written by FoMoCo engineers that detail the development of the car. These have been in the public domain for years if you knew where to find them. Some guy sells them on eBay for $100. Now you can get them right here...
