well, i dont technically need the actual bins... but the shelf that the bins mount to that takes the place of the back seat is what i REALLY need. i converted my S5 to S4 seatbelts and used interior panels. and the S4 panels are closer to the body, so there is a big gap between the bin shelf and the S4 panels... so i need the S4 bin shelf and carpet to take up that gap. joo know?
