Yes, its factory. My dad had a 67 Hemi GTX about 15 years ago. Got a chance to speak to the guy who restored it, back in the late 80's, and he still had the factory Hemi Engine fender tag for it. He kept it as a suveneir. There is another 67 Hemi GTX in a neighboring town, survivor, other than an outside repaint, and it doesn't have the tag.
