“Special” Trim

Don't think anyone repops those just the 87-93 door belts

You probably need to remove the door panel and see if you can get a look at them from the back side. They look like push in clip type. They have probably hardened over time.

I've never seen a molding like that on a fox. The clip looks familiar but I can't remember what it was on.

You do have a few options to resecure them. You can use layers of 3m tape or universal screw stud type that use a nut on the back side. I'd rather go the 3m tape route after straightening it back out.
