to have3 seatbelts in the rear you need a pillar support you have 2 rear pillars one either side (BUT the CENTER ONE is a LAPBELT ONLY) only adjustment is to LENGTHEN OR SHORTEN THE STRAP this buckle end fitting should not fit the 2 other belt clasps as they are a different size it was like this on my mondeo car.
