'72 Dart Swinger (2-door hardtop). There are a few sedan pieces mixed in the pile of parts (I recently discovered that the windshield was a sedan and was 1.5" too tall to fit the hardtop!)

So anyone know what these two trim pieces are for? Maybe sill extensions?
thanks.

looks like the trim piece for the bottom of the rear side panels just behind the bottom of the door opening??? Don't know if it's there to hold the floor carpet behind the panel?

Roof rails over the door vent windows.

Yep, roof rail channels, front section. Holds the roof rail seals.

We have a winner! Thanks.

I haven't put the long roof rail on yet (waiting for the foam sealing tape to arrive), so hadn't thought about what happens at the sharp corner to the A-pillar

Those parts get foam tape too...

I figured as much from the remnants still adhering... Just finished putting both roof rails and weatherstrips on. It's looking like a car now. Except for the missing windshield and back glass

CarID decided today (after I bugged them) to send me out a new back glass "free of charge" and they're still working on getting the defective one picked up. Of course, I already paid for the first one so I'm not getting anything free. Any decent customer service rep would have already sent the replacement!
