This is an easy up grade for your interior. You don't need any parts from the old seats. The instructions are minimal, but it pretty much common sense. Make sure to get the adapter (STP1) and go to the hardware store and get 8 bolts for mounting the adapter to the floor.
Excellent seats! Comfortable and sporty, with a classic look. REMEMBER TO PURCHASE SEAT TRACK ADAPTERS ( part number STP1,STP2 or STP3 )
