Sorry to contradict you, but there are a couple documents out there that say differently. The FoMoCo picture of Shelby badged Mangusta, and the one page flyer of yellow Mangusta with Shelby refences on the obverse. Ford did some marketing work with Mangusta and Shelby but that was not to be.
Also not quite sure what Brock claimed he wasn't involved but in the March '66 R&T he took credit for his body design work and blew his own whisle before DeT took all the credit. The spine frame FWIW is basically a stretched version of the Vallelunga.
