I never myself saw them from the factory. I owned many 72 Demons. I did have a ribbed trunk with the spoiler cutouts . This was on a 72 twister but did not have the spoiler on it. It did have the same inner as a 70 - 71 . 72 demon hoods were on there own also they had the snorkle holes and the twin scoop holes and the hinge threads were fixed and did not move as a 70-71. I am not sure if they had the hood pin holes on the inner or the dimples on the fender support to drill but I can look. I have all three years here.
