Anybody bought a genuine nissan tailgate lately. I just bought a tailgate from a guy who told me it was genuine but it looks the same as the taiwanese one I already have.

I have an 85 ute and the original tailgate has a slightly wider top rail on it and also has the hooks for the tailgate chains welded on horizontally (when tailgate in closed position) wheras the taiwanese one has these hooks welded on vertically like a 'J'.

I'm interested in any way to confirm for sure whether my new tailgate is genuine or not. I know the top rails on the utes varied slightly in shape from the early to the late models but did the tailgates change to match (ie. is there an early and a late style of tailgate??
Any info appreciated.
