Bench seat tracks - 2 door to a 4 door

Are the bench seat tracks the same, whether they come from a 4 dr or a 2 dr? And what years are interchangeable? I have a split bench with the fold down armrest from a 73 Dart Swinger that I would like to use in my 67 Dart. The 73 seat tracks are pretty rusty, and I would like to find some nicer ones. There is a salvage yard that I go to that has a lot of old A bodies. Thanks for any info here!
