OK, visit to dealer has (hopefully) cleared this up:Crazy Paul wrote: I just looked up my records from Feb 2013 and the 2011 Holden Caprice rear diffuser bought from Holden at that time was Part Number 92159840.
So somebody needs to actually view what GM are supplying there in USA under Part Number 92159840.
You might get lucky and not get the smooth Chev PPV version.
92159840 is a PN that went active in GMNA parts on 9/1/2012. This is the part with the "vented" appearance in the post above.
At some point in 2013, there was a PNC (Part Number Change) to 92204154, which I'll assume (at some risk of being wrong) is the smooth version used on the majority of 2011 production PPV's.
According to dealer, even though 92159840 is a superseded number, there does appear to still be remaining inventory at the Lansing SPO location. If someone wanted to order one, it needs to be made clear that you want THAT PN, not the replacement PN version.
