Hmmmm.....I'm not sure on the '78, but on the earlier cars, originally, the plastic trim was secured to the doors with plastic rivets.
The replacement plastic trim is held to the doors with screws, and the hinge is held to the door with screws from the factory.
Are you saying that your hinges are fastened to the door
thru the plastic trim, and not directly to the doors themselves??
