3/4 Ton Dodge WC Fuel Tank

[motto]

I am in need of a 3/4 Ton Dodge WC fuel tank. It is for installation in a Command Car but a tank for a Weapons Carrier, Carryall or Ambulance will do or can be made to fit.
Tank does not have to be in good shape so long as it is repairable.
It would be best if any tank available was located in Australia but if not then a US sourced tank would be my next option.
