Hey guys/gals. 
  
I am looking for a part that is not available in the US and only available on UK and Middle Eastern Spec Z33s. As far as I know US and Japan spec Z33s were not fitted with what i am looking for. It is the finned rear pumpkin, not the finned cover that is available via Nismo but the entire finned rear pumpkin. Anyone have a inside line at a dealer or a junkyard perhaps where I can pick one of these up? At this point if someone could provide me with the official part number I would be thrilled to have that even that. I am looking to pick this up right after the holidays within the first few weeks of the new year. 
  
Thanks in advance, 
Kwame 
  
P.S. Here is a picture of what I am referring to: 
  
(The part that has the black fins underneath it, not the finned cover that you see right in front of you with the drain plug on it.)
