The issue is that with GU2 patrols the lower hook extends too far down and fowls on the rear aluminum bumper step. This genuine Nissan one has a flat bottom, i would ask my local Nissan but here in Canada they would have no clue as the patrol/safari is not a locally offered vehicle.
I thought someone in AUS might have better luck or even access to Nissan FAST parts database.
It is a newly introduced 2015 part for 2015 Y61 Patrols in places like UAE, Saudi Arabia, Giana, etc...
pretty much if you google any 2015 y61 Patrol sales brochure its listed as an optional part, just no listed part number.
if you look closely at the picture above you can make out N01026 which seems like the last bit of a Nissan part code
