the eternal search for a proper red mirror housing has after 3 years drawn a blank, so i have to do the fiddly but doable task of taking my red one apart and putting in the mechanism from a working black one, one small problem, the control wires are held in place by a triangular washer type thing that has corroded away on ALL the mirrors i have, so as a result no way to fix the wires in place. and even better fiat dont sell it, only the entire unit (£50 + vat...no ta) any ideas anyone?
