I am attempting to locate/purchase a complete plexiglas sliding door assemble to cover the Westerbeke instrument panel on my 1987 O'Day 40. I have attached a picture of the assemble which I believe was standard equipment. The assemble does not have any identifying marks and I have been unsuccessful in identifying a manufacturer. The approximate measurements of the assembly are 17 1/2" x 10 1/2". Any help would be appreciated. Thanks.
