Fridge freezer door hinge repair

I have a Fischer and Paykel fridge freezer (model number RX611DUX1) and a part of the right hand door (fridge side) bottom hinge has broken. I would describe the part as the bush that sits on the pin which allows the door to raise as it swings open (and which also limits the extent to which the door opens). It seems to be shaped similar to a figure 8 or two circles with one part attached to the door and the other located on a pin. I am looking for someone who can source and fit this part.
