I believe that in the original position when the rear seat bottom was installed that there was a gap between the seat bottom and back that was large enough to see the rear floor pan. By mounting the seat bottom back further the problem was eliminated.



If that was the case,then Cuda convertibles would have the same double bracket too. They use the same convertible top frame as the Challenger,and the seat is in the same position. I still believe it is because there is a two inch wheelbase difference. The Cuda has a 108 inch wheelbase,and the Challenger has a 110 inch wheelbase. The difference is found between the rear of the door jamb and the rear wheelwell. If you look at the photos of the Challenger convertibles double seat bracket,it is about two inches difference.
