So I’m usually late to the party but did not see a thread with this Documentary posted here. 
Just watched this last night and I will say I learned a lot.  It was pretty well put together and the number of interviews with the Shelby American drivers , mechanics and retired Ford and Ferrari folks that were a part of that history was really cool.   Watch this soon if you like all history related to the Shelby American days.
