Well, as I dig deeper and deeper, I keep finding  things POs have screwed
up, but this is the worst, it could kill someone.

The plastic clip covers on the adjustable side of the belt were all taped
up, and a mess.  I took the tape off and found that on one the metal piece
that the belt loops around was re-assembled improperly and then taped up.
If the belt had ever been needed the clip would have pulled right off.  The
other clip was so rusty the belt couldn't be adjusted at all. They were
completely useless.

Take a minute to inspect your rear seat belts to make sure they adjust
easily as well as for fraying, especially the passenger side belt, which
runs around the seat mechanism.

I replaced them with belts from
