Back vinyl bucket seat repair help

They definitely look like Mopar seats. I would suggest the you post a few shots on the upholstery from the front and a pic of the seat hinge area under a title like, What year and car are these bucket seats from? I think you'll find out pretty quick. The catalog says the switch was 12/1/1970 which means all 70 cars and early 71 cars, then a mid year switch to the new back. From the pictures it looks like the earlier back has the release button for the seat back placed in the plastic back molding, I know 70 seat backs had the button sticking out of the metal hinge cover...
