71 and 72 hood question

the 70-71 hoods have a different hood adjustment system at the hinges. As long as you use the hinges that match the hood (70 or 71 hood and hinges or 72 hood and hinges) you are good to go on any 70-72 Dart or Demon. Mix them up and you can't install and adjust the hood properly.

By the way the 1970-72 Plymouth front end (fenders, hood, grille, etc.) is unique to Plymouth and the Dodge pieces are unique to Dodge, No Scamp came with a Dart style front end, Scamps came with Duster front sheet metal, just like every Demon had a Dart front end.
