72 Duster Hood Question

I know from an expert that a 70 and a 71 Duster hood are identical and fit both of those cars but will not work on a 72 because they are not adjustable at the hinge area. I would have to change out the hinges on my 72 to make a 70 or 71 work.
What I need is for someone to give me a pic of a 72 hood hinge area and someone who has a 71 hood to do the same and educate me as to what I am looking for. I have a line on a hood for my 72 but I am not sure what I would be looking for when I inspect it. Owner of the hood not sure what year it came off of.Thanks.
