seatbelts for car

[Henrietta]

Just bought a transporter as no 4 due soon, but middle seats only have lap belts and as we will probabl;y end up ferrying extra kids would like to fit lap & diagonal belts to middle seats. Google doesn't seem to be coming up with anything, so I turned to faithful mumsnetters... hope you can help

Anyone fit them within Halesowen/ west mids area

We had a Mercedes and could not change the middle lap belt to a diagonal belt.We bought a discovery, it has 7 diagonal belts.Sorry I can't give you any more advice.
