As near as I can tell, the first independant article on the continuation cobra's may have been the following;

Lamm, John. Shelby Cobra 427 S/C. Road & Track v43 p66-71 Ag 1992 (Ag - August??)

"The Shelby Cobra 427 S/C was designed by Carroll Shelby in 1964. Shelby built 57 of the cars that year, but he had the parts to build 100 cars. He did not begin to build the remaining 43 cars until several years ago, and he has since finished 8 cars, which are all made from the original parts. Because Shelby registered the 43 unbuilt cars in California in 1965, the recently finished Cobras are not expected to meet the anti-smog rules that went into effect there in 1966. The results of a Cobra 427 S/C road test are presented."


Note that the registration problem in California may be coming from the 1965 vs 1966 registration date, it's a smog issue - not what I assumed to be a "did they really exist or not issue". I don't think I have this article at home - but I'll see what I can find.
This was found under a 'google' search for continuation cobra, california

I couldn't find anything yet on the claims from AC that there were no unaccounted for frames - will keep looking.
