There ya go! Glad you had them and found them.
Mine didn't come with a backseat originally, so no holes. Actually, a PO had drilled holes for the seat, but they weren't in the right location. Luckily FORD actually marked the holes for both the seat and the belts, so I knew exactly where the were supposed to go, just had to go through the effort of drilling the holes and welding the various nuts to the underside.
