Hood and Trunk Lids

Do Hood and Trunk Lids have specific year part numbers and how do you read them. I have the factory hood for my Duster, and the guy I bought the car from drilled a bunch of small holes for two small scoops- not factory scoop car. It's pretty beat up. I would like to toss it out. 74 Duster-From one 74 to another, are they all the same part numbers? Thanks for any help
