Need help from someone who has installed headliner in a 64-66 Dart

Nope, no clip. The divot in the roof rail and curve of the bow should keep in in place.

It's possible you have the bows in the wrong order, or that the bow is bent out of shape.

Thanks a lot..... I kinda figured that and will wait for warmer weather so the headliner material is a little easier to work with and will play with the bows a little bit.
