From what I understand, the story goes (not saying it's true, who knows) that Chrysler only put the pentastar on the right side because that side is visible when parked on the street- and they could save fifty cents by not putting one on the left side. But in OZ, you guys drive on the other side of the road and park on the other side of the street, so a left hand emblem would make sense on an Aussie Dart... go for it!
