1968 GT/GTS Dart Seat emblems

Were there any metal backing plates behind them?
I kinda thought there should have been but the clips were the only thing there. I guess because these emblems are smaller, idunno. You can still see the adhesive on the clips, thats not rust. Its factory though. These seats are original pieces. The emblems go onto the seat covers then the covers were pulled over the foam. The knap sack material was very fragile so I believe the seats have never been touched since assembled.
