Colin Hyde is producing kits to build segmented aluminum interior end caps. This might be your best replacement option, unless you can source a used part from a trailer locally (not likely you will find one).
Welcome to the forums. A picture would really help to determine what you are looking for. Are you refering to the interior end cap, or the exterior roof vent? If a tree hit the exterior you will also need some aluminum panels. They are available.
