69 barracuda fastback back glass gasket

As I look at the wife’s ‘67, I used a lacing strip. AKA, lock strip. This thin rubber goes inside the channel of the main gasket to “Lock in” the window.

I do not know about ‘68 & ‘69 models. I can’t find a ‘67 window rubber myself. I’ll score a 69/69 later and use that style trim retaining clips for the trim that needs to be done.
