Are you able to tell me when did you buy the OSG, and what is the part number for it?

There seems to be a heap of different versions/part numbers for the OSG diff for 370Z.

If I order one, there is a 3-4 month wait from local OSG Dealers here in Australia. But RHD Japan website:

says they have one in stock, but from their product page it looks totally different and has a different part no. than the current on the OSG official page:
