After studying both, I'd have to say it's highly unlikely that they are the same car. I could see someone making Lucifer from Double Zero, but not the other way around. Lucifer has a different hood with quick release pins, side scoops, rear spoiler, no front grille/lights, no wipers, no door mirrors, no 'Mustang' text across the trunk and extra suspension components at the rear. You would need to restore it back to near showroom condition before turning it into Double Zero. This seems like an odd thing to do to a race winning car.
