I've done a quick search on the named "copper" heater cores, and none of the cars for them were brought into Australia.
Also, the URL supplied goes to an empty web space - no site there?!?!?!
So, who can help me with the email address of a radiator repair shop in the USA who's a bit tech savy? Eg: Someone with a PayPal address for easy payment, or can take credit-cards over the phone or the net?
I don't want to buy an entire heatercore, so I need a repair shop.
