I was unexpectedly stranded today when the top neck of my radiator decided to part company with the tank. Clearly a fairly standard problem with heat affecting the plastic of the tank and neck and causing it to go brittle over time.

What seems to be more annoying, is that I can't find a replacement in Australia. Does anyone know of a potential supplier? I have tried my usual radiator man whose AdRad catalogue listed only 760 4-cyl and 740 units which are obviously too small.

Ideally, I would want to upgrade to a full copper unit, so would be hunting even for one of a close size to the original from a different car that is more readily available. I am quite happy to fit a separate auto trans cooler.

Any ideas would be much appreciated. The car is a 1988 760 GLE.
