Welcome aboard James , your life will never be the same again .

As Keith said completeness is the key , engines and power trains etc can be salvaged from other blitz's or civilian trucks but it is things like the bodies and components that are specific to blitz's that are important .
From your location I would try the various stations to see what they had on their vehicle dumps . A good number of Blitz's etc were sold from the disposal sales in Darwin after ww2 .

All the best
