I have the rear seat trim panels and rear seat from a 72 XR-7 conv't, all white pieces. I just sold the front seats and right door panel to another board member today. The rear seat trim panels I have are for power windows. They have a larger square cut hole for the window switch where a manual window car has a small round hole for the crank shaft.
If you don't have power windows, and want to upgrade, I also have a complete power window setup. All four motors, all the glass (the door glass is unique to power window cars), and the complete nose-to-tail wiring harness. This won't be cheap though!
