In search of yacht part finding business or person

Hello, I'm in need of a stock radar arch and aft deck roof for a '88 Carver 4207. I've been on the search for months calling a few random salvage yards to no avail. At this point, I would just like to find those parts and don't mind compensating someone. If you know of a business or individual that specialize in that or if you happen to know where these parts are please comment below. Thank you
