I spent part of the day cleaning and painting all of the seat track trim for my bucket seats. I figured out where all of the covers go for the tracks where they bolt to the floor. I also have 6 upper track covers. Im not sure why I have 6. I thought they just go on the front of the seats. Do they also go on the back ? Either I picked up an extra 2 or Im short 2. Can anyone tell me where they go ?
