Converting Newage JDM to 3x3 point seat belts instead of lap belt
 

Pending the sale of my UK spec STi, I'm hoping to buy a hawk JDM. How easy or not is it to convert the JDM to have a 3 point seat belt on the middle seat instead of the lap belt? Can a UK spec rear shelf that holds the over the shoulder strap be swapped over?
Having 3 kids I'm not keen on only a lap belt for one of them to use.
Cheers

ISOFIX seats with built in straps?

Sorted it , Scott at scoobyspares will do it. Just need to sell mine then I can buy Martins white hawk.
