Did any year of Duster come with a stock coolant overflow tank?
'73-'76 had them.
They looked similar, but there were 2 different versions. The '73had 2 rubber lines from the cap, 1 to the radiator, and a discharge line clipped to the side of the body.
'74-'76 had one line to the tank from the radiator, the overflow was a molded-in part of the body.
The mounting bracket was slightly different between the two, also.
They are interchangeable.
You will also need to use the later radiator cap for the system to function properly.
