Re: WD420
Yes this part is available, Connect for one can supply, however was called last week to one with same (common) prob and I was out of my own van stock of these so I carried out a repair with tub repair kit.
Make up the mix then apply to the four tabs and securing points at rear of facia panel, refit panel then tell customer not to use till next day to allow mix to set.
My customer phoned to say that it works a treat even better than before it had broken.
