I bought two blades amd arms from fords, plus 2 x left clips top attach arms to blades, around £25-£30 from memory.
They are std fitment also on a large number of volvos.
You can only get the left side clip between arm and blade, well think it's the left defo only one side but can just be put upside down to do the other side no problem just means one has water pipe for washer on the underside one on the top side, but both work perfect.
