I would have thought that you could justify from a safety point of view fitting a 5 point and having an ineffective anti-submarine belt because this just makes it equivalent to a 4 point, although it might look a bit silly.
If you do fancy a swap I am looking to sell my Luke 4 points and buy some 5/6 point
What colour are your Luke four points?
/tart
G
Black
Are they 2 or 3 inch shoulder belts?
