I understand the possibility of the sticker being put there by someone, but I don't know who would spend the money on one just to cover it up. If they were to have taken it off, I'm sure they would have taken off the yellow Mopar decal at the top, too. The fact is it's still there. Look closely at the detail pic. Most of the ink is gone, but the actual vinyl is still firmly attached to the lid. What I'm trying to determine is the likelihood it came off a Hemi Road Runner. I may never know for sure, but a definitive answer against it is impossible. Either way, it's just as you said, a nice piece of wall art.

Morty426, the spacing is for the 69-70 383/440 4bbl and 69-71 Hemi.
