The rear seats are the same size and shape, all you would have to do would be to swap out your OEM seat pans onto the ST170 seat pans. Other problems you might encounter are the seatbelts and airbags. If the seats that you are planning to install are not from the same year, then you will have to switch out the seatbelts and air bags on the front seats.
