Congrats on your new Sunny! and welcome to the club.
I am not sure what the older mid 80's trim molding looked like. Can you post a picture of the rail you want to put the cover on? We can help search with you. They sell many types seal/screw covers and how the seal attaches to the molding and how wide the molding groove is, is required to buy the right one.
Please post a pic of the molding and how wide the groove is the cover will fit in. If you cannot figure out how wide the groove is since you have never seen one, place a tape measure over the molding and take a pic and post and we can help.
I had thought that possible some of the older camper roof line moldings did not have a screw cover. Not sure if Sunline used that brand or not. Again by the pics we can see if your is setup for a cover or not.
Hope this helps
