Dart 67 rear windshield gasket source?

NOW I see them at Precisions Site...Holy Cow there are a ton of them! Lol now I’ve gone from not finding any to not knowing which one I need! my chrome rear glass trim did not have clips, they just pulled right out of the decayed rubber seal. Thoughts?
I'm not sure there. The lock strip on the front window had no clips. It sits in a groove especially for it with my make/model window gasket.
I did call and talked to them very helpful.
