Steel or Alloy Radiator Overflow Bottle GU4

Hi guys!

Looking for a steel or aluminium radiator overflow bottle for the coolant system on a Nissan Patrol Wagon GU4 2006 which originally came with a ZD30.

Think there is a Chinese company called Apollo Racing on eBay selling these parts. However, first wanted to check if anyone local knows where to source this part.

For reference here's a picture of the engine bay, and a close up on the overflow bottle.

By the way I am located in Brisbane. Cheers and thanks, any tips are welcome.
