Anyone have a more complete list of Nissan VIN codes?

Hi,

The VIN key on this site (Nissan Vehicle Identification Number VIN Decoder | Nissanhelp.com) seems to be one of the best available, however, I'm hoping someone can point me towards a more complete list of codes. Many of the letters on my South African built vehicle are not mentioned, and I'm curious to know what they all represent.

Thanks,

Rob
