T-Top Obsolete weatherstrip need for resto

[Chris Wetter]

I am desperately looking for the door glass guide weatherstrip for my 83 t-top. According to Ford they have none in the country and there is no aftermarket. It is the weathersrtip that runs up the top of the mirror then down the face of the mirror and into the window channel. It looks like a backwards fancy number 7. Any help would be great. I have already tried most resto places and they say I am S.O.L.
