Seat upholstery choice

I found out that I don't have a fold down rear seat. It was not bolted to where it should sit that's why I could fold it down.

Can't get hold of Legendary when i press submit button nothing happens. Because the buckets in the first link says it fit Dart Sport/Duster nothing about Dart Swinger but in the picture it looks like mine buckets. Is this the ones that should fit then?
