http://www.petersen.org/default.cfm?DocID=1014&cat=Shelby&ExhibitID=264&index=15 Gives a brief description, and I'll get into this in more detail later, but briefly... the S.D. Auto Museum had a couple incredible Ferrari's on display awhile back, and a Scaglietti Corvette was there ( and forever on my camcorder tape, before I had a digi camera) and I learned that the racecar drivers / owners who were so far from the US source for parts in the 60's while racing in Italy, tried to get something happening as a collaborative effort that would achieve race cars that could be quickly and locally repaired.
