Thanks guys, yes I've been scouring trademe and have already contacted the ones listed here, no luck so far. They all have the oval type, not the round type, except for two of them that are missing the intake pipe. Ditto for the QLD one, it is the oval one. It has to be the HSG part, not the standard RVR one.
I can't easily make a part as I'm 4 hours away from the car and have nothing to go off, can't use a pod as I have to get the car Blue-Slipped.
If someone has the part they could loan me so I had a 'template' to work off, I'd be happy to pay them well for the trouble.
If anyone has a photo of the pipe as well, it would really help with getting one, often the wreckers have no idea what they are looking for and a photo would really help heaps.
