NEED SCHOOLED ON A BODY HOODS

I need someone to school me on 69 barracuda & dart sport hoods. I thought I knew how to tell then apart. The original hood hinges on my 69 barracuda are non adjustable. The adjustment is in the hood. The later hoods ( 73-76 dart ) the adjustment is in the hinges. The mounting holes in the hoods for the darts are stationary. I have 2 67/68 barracudas & the mounting holes in the hood move for adjustment ( the same for my 69 ) I bought a 73 dart sport hood from a friend some time ago. IT WILL NOT WORK There is no adjustment to it. Now, I bought a hood from someone else. I was told it was a 69 hood. It is partly my falt, I didn't look at the hood in that area. The hood I just bought will not work. I posted some pictures. The bronze hood is the one I just bought. The gray hood is from a dart sport. The green hood is a 67/68 barracuda hood. You can see on the 67/68 green hood that you can slide the bolt holes for adjustment, the others you can not. Am I right in my thinking ?
