Freelander 2 o/s/r seat belt replacement

Hi, I've got a FL2 2006, and it's going to fail it's MOT because the o/s/r seat belt is fraid from rubbing against a car seat.

I've ordered a replacement seat belt from ebay for 2006 FL2, but a 2005 FL1 seat belt turned up and looks different. So that's going back.

Does anyone know how easy it is to change. I assume it's connected one end to the pillar and the other end under the rear seat. I was initially put off because the pillar has an air bag and I didn't want that going off.

Just need to track down the correct part now!

Thanks in advance for any advice.

If your worried about SRS systems, just disconnect the battery for 20 minutes before working on the vehicle.

The rest of the job is very easy.
