1966 Dart GT Roof Trim Help

1966 Dart GT

Chrome/Stainless Steel Bow roof trim

Internal clips or attaching methods

Had an internal clip that holds the roof trim in place that wore out and broke.

I was wondering if there are any other attachment methods or a way to buy the clips individually

Any ideas would be great

I am trying to figure out a way to fasten it to the roof without removing the headliner

Thank you!
