Identify trim pieces

[supertruck]

The Dart (73 Sport) will be back from paint next week and I'm getting the interior pieces together. Can anyone ID these two? They're about 11 1/2 inches long and I marked them passenger and driver. Since it's been 4 years since I removed them, I can't remember where they go. Thanks guys!

Sill plate extensions from the sill plates to either side of the rear seat area?

Sure looks like it.

Hadn't thought of that. Thanks! Knew FABO would come through again.
