You'll find these pricey, especially from Volvo. I'm afraid if it's new you want, there's limited sellers, and stock, at any price.
I rebuild them, but before you get involved in this, read my FAQ stuff about moving the whole assembly. Or you'll be crying in you beer. UK summers kill these, and you're in Spain!
