72 Duster Parts

My ex husband had taken all the interior pieces off of his car because he planned restoring it but never got around to it and later sold the car. Now all these parts are in my garage and i need to sell them!! Could someone please help me know about pricing them..it's all the interior pieces and trim. I have all the bolts originally used, original seatbelts, original radio, 2 different bezels, gas pedal with linkage, chrome trim, dome light, grill, headlights, air ducts, tail lights, and some sort of flat pieces. Any help i would greatly appreciate!
