Sweet Pea: Photos of the fiberglass cover with the slide-in teak wooden moulding/rail are on the first page of 2nd Byte's Photo Album which is the first one listed under Photo Albums.
Strangely enough, my '87 Cruiser was one of the first out of the new Cruiser mold (January 7, 1987), and (I'm the 2nd owner) never came with any cover for the backside of the helm station. Since I don't sleep up there or spend time there (my 150 lb Great Dane, Shadow, does, though), I've never considered adding a cover, as it would only impede access to the wiring center of the boat. There are quite a few in-line fuses there that sometimes need checking, etc. Happy Thanksgiving! Joe.
