What year Zed is it? Might help.
Pretty positive you just need to get the cubby hole and top portion of the centre console (section above heater controls etc Piece on right in picture) then just retro fit it into yours after removing the SatNav etc.
I'd try the usual suspects on here; zmanalex, Clark Motorsport, R35LEE, Shades Rs first. Then the "350z parts for sale" section and then move onto breakers from eBay etc if still no joy.
