960 windscreen seal split

[cheeky_chops]

hi, my old man in spain is abit stuck - his old p reg 960 barge is leaking around the windscreen. He has taken it to some autoglass type people and apparently they cant get the window any more, let alone the seal!! The local Volvo dealer arent any use either...

Is it still available and can you get the seal seperately? tia
