Australian body parts are not interchangeable with the US bodies. I have an Australian body 33 willys that I am making into a US 5w coupe. I have imported lots of parts from the US to find they don't fit eg. Garnish moulds Australian sedan front doors are 1in longer. Also I have an very early 33 body from holdens that has normal opening doors but Holdens used 33 Chevrolet hinges so when you use original US hinges the doors don't open as the top and bottom pins don't aline.
