Second Ed's comment
We had to do something about our seat belts in the Superior immediately when we got the coach, because ours were to short. Told Paul when he called today, that the GM buckle medallion looked lousy and the narrow belts looked disproportionate to the size of the interior. We sourced a wide set of belts with large buckles and the Cadillac crest in the center button. Retractor belts, plastic retractor covers and devices. Only difference is that we had our buckles rebuilt, then we had longer seat belt strap replaced for the shorter factory length. The tang does not retract past the cutout, into the retractor, because of a shoulder on the wide style chrome tang. The difference I see between the narrow and wide retractor take up belts. The original GM belts were to short to use even with the seat as far back as it will go. I strongly feel they were installed just to say they were there. I have the center set of belts wrapped up and bagged behind the seat in this picture.
