Body Parts Swapping with Different Years

The salvage yard should have a Hollander interchange manual if they have been in business for awhile. Most yards today get their info from the manuals on computer but I'm not sure if they go back that far.
I have a '73 Dart Sport also. I 'believe' the fenders will need to be '73-'76 Dart, doesn't matter whether 2 or 4 door. The deck lid is the same as a Duster. I think all years Duster will interchange, except some didn't have the rib down the middle.
