Okay so in addition to have a '92 Cherokee Laredo for my toy I also have a '99 Grand Cherokee Limited for my daily driver and low and behold my 100 pound grandmother somehow managed to break my seatbelt retractor on my right rear passenger side. I managed to get a working retractor from a junkyard but am now stuck with how to switch out the belts if that is even possible. I have no idea how to do this so any help is appreciated.
