Hi, I'm new here, and I want to ask about a S80 rear speakers. I have S80 1999 and I need to replace the left rear speaker, part No 9472374. I need to know if it is the same speaker like on S70 or V70 99'-00'. Also I want to know how works Headlight Wiper Blades (http://www.fcpgroton.com/product-exec/product_id/8682/nm/Volvo_S80_Headlight_Wiper_Blade_Set_99_04_/category_id/221). Thanks.
