a complete used taco whip assy from a junk yard is about $30 bucks or you can get the taco whip from a dealer for about $50 or get the motorized unit for $80-100 or more.
you don;t have to remove the trim, you simply pop one of the plastic rivets out in the wheel liner and pull the liner back until you can get your hands in there and is connect and remount the new one, it won;t break so just pull on it till you get the room you need, the hardest part of the job is routing the wire behind the glove box and making it look stock or factory, which in it's self is that long part of the job when i finally switched over.
