Seat Interchangeability.

I have a 1973 Dodge Dart Custom Sedan with the regular bench seat that is worn out, and is pricey to get recovered to match the rear seat due to getting the fabric and the labor, companies make reproduction seat covers for all seats in the abodys except the one i have,
What seats out of the a bodys will fit bench wise, are there a differance between the segan front bench size and the duster, included is the bench seat i have from the brochure.
