Will 1974 Dart swinger seats fit in my 1972 dart custom?

I recently found a front bench seat from a 1974 dart swinger, and was wondering if anyone knows it if will fit in a 1972 dart custom 4 door. Someone is selling them for $100 and they're in decent condition. They seem similar, but haven't seen them in person. Please let me know if anyone has tried doing this before. Thanks!
