Wounded window winder

[e2e]

Happy new year folks. Just spent two weeks at the beach, but that¹s another
story...
My 1990 200TQA has eaten its drivers (RHD) electric window winder. The
plastic drum that the cable spools around and back gave up and has eaten the
cable nicely. Hooray now I can be a member of both team door handle and team
windwoe!
Ok so how do I extract the cable off the window???
The cable does not want to come off the rail that the window runs up and
down neither does the rail want to come off the runner that is attached to
the window, nor does the runner want to come off the widow.
Now wire cutters will work in a flash but that won't help me in the long
run.
Do any of you kiwis out there have a spare window winder, mine is
electrically 100% all I must have is the plastic drum I can at a pinch get
the cable remade but would rather replace the whole lot.
