has anyone taken out their rear seat and replaced it with something more space sensible. i dont like having a back seat in, but sometimes i need room for everyone. i was thinking about putting seats from an old toyota landcruiser. you know the ones that fold down from the side. i cant thing of anything else. i have a storage box that i built that takes up the rear half of the back. does anyone know if it is legal to just bolt seatbelts to the floor and let them lean against the box?
