Hello, I'm helping a friend who has a 2018 Land Rover Discovery. Her dog "ate" (chewed up) the right rear seat belt. The dealer wanted a ridiculous $450 to replace it. I found several used belts with the retractor online at for less than $100. I'm very mechanical but would like some advice. I found a you-tube video but is so poorly done as to be useless. Any pointers appreciated.

 

see if this helps
