Passanger power window and crank sunroof question

[Colin Fiedler]

I am going through my 87 Coupe GT fixing everything that needs it and the
passanger power window doesn't work.  I took the door panel off and found
that the window regulator was not connected to the door panel anymore, it
was just kinda floating/hanging in the door and one of the 2 wires that
operate the window are broken.  Can I get just a new wire somehow or do I
need a whole new assemly?  Also, if I need the assemble, does it carry over
to any other cars like the 4000, or is it Coupe GT specific.  Also, I need a
sunroof hand crank, light beige, anyone got one lying around for cheap?
Audi wants $44....
Thanks,
Colin
