I recently acquired a nice Subaru Impreza wagon but I need to do some replacements here and there. I am curious to know which other year model parts would fit on this Impreza? For example, would I be able to put newer Impreza mirrors on this older one which has the frameless doors? Also, I feel the steering wheel is batteling to turn. Youtube videos suggest it could be the battery. But I am uncertain. I suspect it could be the pump so would a 2007 power steering pump fit? Any advice is appreciated!
