Cobra Histories

[cc8s]

It seems very easy to discover the history of most classic Ferrari racers as they are very well documented on sites like Barchetta. I am trying to find out about the race history of these two cars and wondered if there was a site that would be useful or if any of our resident geniuses would be able to help me out?

The Shelby registry is probably a good place to start.
