No, the 67 rubber seals have no provision for attaching stainless trim. I got the rear window rubber from a junked 68 Barracuda (back when you could still find them in regular junkyards). They were not reproduced then, may be now.
The windshield rubber is available new and is the same for all 68-72 Barracudas and Dart hardtops except for the Duster type bodies.
