I have a 68 dart with bucket seats. What is the easiest way to tell if these are the orginal seats in the car. If not how do i tell what year/ possible make and model did they come out of. They are powered seats they look original it doesn't look like anybody tampered with them the wiring harness to the seats looks factory. They need to be recovered and i would like to make sure there from a 68 dart. Any help would be great. Thanks
