I love when you find all this stuff Keith! You just made me walk out and check on the 65 Formula S engine that I just checked. You are so right. It is added on a thin plate of aluminium. I have seen this Before on Formula S air cleaners but not on the 273 Charger engines! Can it be differencies between the two? I daubt it but I'm not sure! I have the factory decal on the air cleaner in the convertible and that's just a sticker.
Thanks Keith! Where can we found some more input?
