Another "What's this part" thread

Bought these upper door moldings from a vendor at Carlisle.
Marked as 73-76 A Body.
I wanted a clean set, so I bought them.
Get them home, and my Duster doesn't have the curved portion and there's no holes for the lock knob.
Any idea what these are for?

Those are for a 73 to 76 dart or scamp (the "23" 2 door body) they go under the rear 1/4 windows

Thank you. That explains a lot, and now that you mention it, I see that.
