They aren't recorded. However I seem to recall in 'ACtion' that a request was being made to AC for a list of 'continuations'
Most of the information below is from Trevor Legate's 'Cobra - The First 40 Years' (with a few additions on my part).
The following complete cars and rolling chassis were built to original specifications before 1996: CSX 3056-58, CSX 3070, COB 4000-01, CSX 4002 (title transferred to COB 4000), CSX 4003, COB 4004, CSX 4005-13 - all 427 style cars except COB 4004, a RHD 289 MkII initially exported to Finland (but apparently now back in the UK).
AC produced a further 16 continuation 427 cars, 9 of which were sold as complete cars for racing in the late 80s /early 1990s with a further 7 chassis in various states of completion - chassis numbers from COX 6133.
There were also two 289 FIA cars produced after Mr Lubinsky took over, the first with chassis number COB 1001 (in 2002), the second COX 2610 (in 2003).
Then there were the 8 427 'continuations' built between 1998 and 2003 with chassis numbers COB 5001 - 5010 (nos 5003 and 5009 not used).
Since Trevor's book was published - COX 5012 (Trevor's own car), RS 5037 and 5038 (Ace 2.6 bodies/with Cobra MkII chassis built in 2004 and completed later). RS 5038 is Gus Meyjes' car and has a 260 V8. The final car to be painted at the Frimley factory, COX 3361 is a red 427. COX 2615, a yellow 289 was also completed by AC Heritage after AC closed its UK operation. AC Heritage has also advertised COB 4007, another 427 recently.
Then there were the 14 cars commissioned by Carroll Shelby from AC with chassis numbers CSX 1001 upwards in 2005/6. There's also an FIA commissioned by Shelby from AC - CSX 7503
Here's CSX 1001
And then of course there are the AC Heritage built cars such as COB 5014:
