The Thunderbirds did not use the winding type of sunroof from Golde. Rockin_kev on this board was able to locate some parts for his sunroof from Golde, perhaps he can tell you his source. Old Volkswagen, Jaguar and BMW sites may be helpful to you in locating original or reproduction parts.
Is the type of roof you have?http://www.my2002tii.com/spring_2005/sunroof.htm
Good luck in your hunt.
