Can anyone decipher manufacturer casting codes

[michael]

Hi all,
Does anyone know what the codes cast in the gear box and diff casings of an NA8 in this case, actually mean. Are they date codes and if so does any know how to read them.

The attached file in "attachments" below (I had no idea how to insert the photos here) has 3 pictures. The first is of codes on the bottom right of the rear alloy dif housing, the second is on the left side of the dif centre itself, and the third is on the right side (I think) of the gear box.

Can anyone shed any light on these codes.

Thanks for your help

Michael, unfortunately no change as far as I know:

I had forgotten that I had asked the question more than once in the past.

But to my credit I did add pictures this time.

Surely someone must know something about such an important topic!!!!!!!

Boyracer's the only person that comes to mind - in talking about the NB 6 speed GB he mentions an identifying sticker - see last post following page:
