Part help needed - 2003 4motion rear suspension arm

[ScruffyDoug]

As per the title, my 2003 1.9 TDI 4Motion has failed it's MOT due to a fractured offside rear suspension arm. As is becoming more and more evident with this car, it seems nowhere, not even VW, have spares anymore (found this out last year when trying to source replacement exhaust).

Can anyone suggest anywhere that might have one? New or from a scrappy, at this point can't afford to be picky as otherwise it's the end of the road for the old girl, all for the sake of a single part.

Already tried running quotes through PartsGateway and Breakeryard, but no success. Any help at all would be hugely welcome
