look for "control cables" in the business phone book.
Spain will have cable makers as does France, Holland, Germany, and just about every country in the EU.
If the short length of cable on the deck side of the cable is breaking, that can be replaced, I do & get it done it regularly.
However there is something wrong if they continually break there.
Some photos of the deck with the cable attached & the blades both on & off would be helpful.
Undo the deck & slide it out sideways far enough to get a good photo.
