I saw some talk of this here and I knew mine was in the wrong location, the person I bought the car from put it on the radiator shroud. After doing some research I actually found the old indentations of where the original decal was under the paint, I am posting the pic which I think depicts better than any I have seen, I also think this was a goof by engineering because it doesn't fit the area, you might be able to get it to line up better, perhaps the assembly line was just "whatever it doesn't fit, so ...." and some ended up slightly off than others.
Here are three photos from my files that show the sticker in what I believe is the correct spot. The red is my car, the verdoro is a one-owner POCI gold award winner (the most perfect '68 I know of), and an untouched survivor '68. That said, I suspect different employees may have slapped them on in different positions as they went down the assembly line.
Those are some of the photos I saw, then when I looked close at my car I could see the old marks where the original one was, I can see how factory personnel would alter it simply because it doesn't fit. With the angle mine is one it would actually fit with careful placement, but since I could where it actually had been that's where I put it.
