Wanted: Port Window black plastic exterior frame

[Jordan Rautiola]

I need one exterior frame for the rectangular side port window for my '81 F-255.  I believe that Formula used the same port window on the F3/233/242/255/272/302 from the mid-70s through the late 80s, so I know there's lots of them out there.  The frame I need screws into the hull from the outside.  I contacted Formula but they didn't have any and didn't know who their supplier was, so my best bet is to find a used one.  Thanks.
