I recently discovered that the area where my drivers side seat belt retractor mounts to the tub was rusted. It was bad enough I was able to tear the retractor from the tub by hand. My question is can I just attach the retractor to the bottom of the roll bar with a bolt, nut and washers? I was also looking at attaching it to one of the existing bolts that mounts the roll bar to the floor but that would be in the way of back seat passengers. The jeep is virtually rust free except for that spot so I'm in no hurry to repair it if I don't have too.
