I also believe that the metal loop attached at the sill is incorrect. Not the mounting. But the belt should go through the loop from the bottom through to the top. It seems reversed in the picture - goes from the top. In the way you have it, the belt can be stuck behind the seat. You should be able to grab the belt on the side of the seat as you sit. Perhaps it needs to be rotated, for the passenger side? Having it correct, should assist in pulling the belt across your lap.....
