Hello ,
Also take a look at the BACC site.

We meet every Saturday in Dublin, CA and have done for almost five years, you will see a wide variety of Cobras from originals, Shelby, Unique, Factory five, etc. etc. in the parking lot.
Make comparisons, talk to the owner/builders and get more than you wanted to know all in one place.
