Sill Plate Extensions

It's been so long since I took apart my 74 Dart Sport (now cloned into a 70-71 Duster), that I don't remember anything about if it had these. If it did, I don't have them any longer!
Anyone happen to have a picture of how they look installed? I won't have a back seat. Will I need them to trim the now carpeted rear floor?
