Does your Patrol have lap only belts in the outer positions as well or is it only the 2nd row centre position? Asking because I’ve never seen lap only belts in the outer positions. All our Y61s came with 3-point belts in the 2nd and 3rd rows, except for the centre 2nd row position.
The last of our AUS vehicles (what we call Series 10) sold in 2016 had a three point belt in the 2nd row centre position. They needed this because there was a regulation change in 2016.
The 2nd row centre seat belt reel is up in the roof which means they have a different headliner. They also only have one a/c vent in the roof for the 3rd row passengers on vehicles with rear a/c, unlike the two vents in the roof for the older vehicles. The belt also has a second buckle which you need to unclip to allow the belt to completely retract into the roof for when you want to fold the seats down. Lastly, there is also significant structural differences (additional reinforcement) in the roof rail area above the LHS C-Pillar to support the mounting of the reel.
The rear outer 2nd row seat belts are different to the fronts as the fronts have pretensioners, which the rears don’t have.
So all in all, with enough time and money anything is possible, but retrofitting seat belts is going to be a lengthy and costly exercise. You’d need new belts, new 2nd row seats, new headliner, new rear a/c ducting and vents, some metalwork in the roof rail and possibly, some metalwork in the C-pillars if you don’t have 3-point belts in the outer positions.
