Does anyone know the part number for this and/or where I can get it? It comes from the factory spoiler for a 2011 Nissan Rogue SV. The spoiler is connected to the body with two bolts and there are four of these plastic connectors. Two of the connectors have broken off which allows the spoiler to move and obstruct the opening of the rear hatch.

I do not know if these connectors are just for alignment or if they actually hold the spoiler in place. The parts diagram refers to a “grommet” which suggests that the pin end of the connector snaps into a grommet, which in turn is fastened to the car body. However, I cannot find any such grommets on this car.

The head of the connector is 9mm and it is 19mm long. The hole in the car body is 8mm.

They're push in fasteners. Google lens didn't find it.
Close, but was a square top for infinity. They are
to hold it in place, as well as an alignment dowel.
Alignment dowels usually do not snap into place though,
they just guide the part to the correct position to be
snapped or bolted in.
