Hi, it is not entirely clear which part you need. First, if you are looking for parts for the passenger side (right front) seat, you need to know if your car was built in Japan or Mexico. Next, decide if you need parts for the seat back or the seat cushion (bottom). For the seat cushion, note that reference #2 includes everything within the box, which includes parts reference #3 and #4. Part #3 is just the upholstery, and you would choose material and color. Part #4 is just the foam.
