Since I now have JDM tails on my BH wagon, I've confirmed what I've seen in pics. The outline on the USDM tails is darker like the bulk of the USDM centerpiece. The JDM tails have a uniform red color all the way around. This means that closer up, you see a difference in the tails. All the pics I've seen of AUDM and EUDM tails shows the darker red outline that matches the darker center piece in the USDM style. Finding a source for AUDM or EUDM units isn't easy, and what few I did see were more expensive than JDM pieces. (Hint to anyone in Australia or Europe - there might be a sideline business for you here.) The Legacy set seen in a previous post that has the darker outline on the tails looks to also be raised, which is what is seen on the Blitzen, except that it seems the Blitzen had that raised part painted body color.
