1967 Barracuda Upper and Lower Trunk Trim needed.

The aftermarket ones are just plain wrong, in that they sell one piece for both top and bottom. Since the bottom is the one that always gets smashed, a lot of people wound up with top pieces on the bottom. But the end profile of the top piece when flipped over doesn't match the profile of the bottom of the taillight bezel — look at the taillight closely — all the angles are different because the back face isn't vertical, it's on a slant.

From the photo, it looks like the aftermarket replacement trim used a bottom as the model (the bottom matches the taillight better than the top one does). In that case, you should just buy one of them and look for a good used top piece, or have one restored. The top is 5X more common than the bottom.
