Actually even though you have a full bench seat you will still have room to place the seat belts. Just put them in the exact same location as they came from the factory. Heck they might bolt right in. I know there are holes there. Between the crack of the bottom seat and the backrest. Behind there should be holes with seatbelts already there. They always fall behind the seats in everyones cars. Actually if you want to chat on the phone you have my number Mark. 4 point would be more work. Im not sure if your looking for an inexpensive way to solve this problem or a quick way or the cool looking alternative. Its always harder to communicate via e-mail.
