hood adjustment

hi, got a question. i've got two 72 dart swingers. one's a rusty parts car that i know still has the original sheet metal. the other had a fender change, maybe more, along the way. i used the hood on the parts car for the other 72, and had to change the hinge's also. the hood on the part's car has it's adjustment in the hinge's, and the other one has the adj. in the hood itself. did they change the way they adj. between 70 and 72 ? thanks, dave.
