If anyone is interested I could dimension my template and you could make your own close out panel. I don't recommend buying the fiberglass part I bought. Maybe it'll fit perfect on your car, it didn't on mine. You can make this from any type of stiff sheet goods that is weatherproof. I used PVC pipe. You can get 1/4" PVC sheets from building suppliers, though this isn't solid PVC. It's cellulose PVC. It will probably hold up just fine. The 4x8 sheet will make 4 or 5 close out panels. Heck, 1/4" plywood would work just fine too. Fiberglass, steel, and aluminum are choices too, if you have access to a cheap supply. This part isn't structural. I wouldn't spend very much on materials to make one of these. There's no need to.
