A reader from South Africa sent the serial number of his jeep to me, asking when it was built. I concluded that the serial number indicated he has a 1966 CJ-5. The curious part is that he has AA’s stamped on the end of the serial number.Here’s an approximate example of his serial number: 8305 211XXX AA ….  It turns out, he’s not alone.

Here’s an example (again from South Africa) of a CJ-6 with the AA’s stamped into the serial number: http://www.4-the-love-of-jeeps.com/cj6-big-red-comes-to-papa.html

The internet also has a few references to others with the double AAs. What I think is going on is that as a part of converting left handed jeeps to right handed ones, the company that did it was also adding a set of AA’s to the serial number. Does anyone know of this to be the case?
