I was wondering if anyone knows where to purchase an aluminium header (expansion) tank for a GTV6.

I have seen them around an have been told they are able to be purchased from internationalautoparts.com ... unfortunately i have been navigating my way around there for a long time and have not yet been able to find such a thing.

Is this my only avenue of investigation or can i get one from somewhere else, preferably in Australia.

Am also interested in one for a 75 .... any takers?

No one else online or by mail order .... I'm a wee tad north of Dandenong
