Would tend to agree with Steve based upon construction of vehicle. The originals and if the SPF is true to form, have the seat base and back as an integral part of the mono chassis. From my understanding, that is not the case in a tube frame car. You have a seat shell covered with foam, which is then bolted to the floor/chassis.
Russ, "The seatbelts restrain your body so it can't move". I guess you are uncomfortable when you drive. Your belts must be as tight as an astronauts'.
Sorry Russ, but you haven't convinced me. If the seat is only bolted to a sheet of 1/8 in aluminum, I would be willing to bet that over time and mileage, the floor, at the seat mounting points would suffer some type of fatigue. We can agree to disagree, however my car will not rely upon the floor alone for a seat mounting point.
