71 Demon Hood Stripe Dimensions?

Well to the best of my knowledge the orange one in the OP pic is Most correct, notice how the front outside edge angles back to match the leading edge of the hood. That being said i have met a few demon owners who have said their car did not come from the factory with the thin black trim line. I also have found the owner of my demon from 73 to 79 they sent pics taken in 75 of the car and on those pics no thin line. i've never been able to find anything concrete on why some demons left without the thin line maybe it was as simple as it being a pain in the A** to do at the factory. so in an attempt keep the line moving faster maybe they deleted it. My Demon is a later build of 4/02/71 maybe the other poster can chime in on a SPD on his demon hood without the thin stripe.
