why not 100%? there hasnt been an american falcon since about 1969/1970, and even still, the last aussie made falcon that pretty close to identical to the american falcon was the xp. since the xr, ford started making the aussie falcon different, and for the xa, it was fully australian developed, engineered and designed. theres bugger all modified to the magna from what i can see. put an american diamante, aussie magna and whateva they call in it japan all together and the only difference will be their driving style to suit their respective countries of origin
