Next I worked on the aft seat floors. First task is to locate and drill the hinge halves. I studied the drawings for awhile because there are lots of parts and measurements.
I measured and double checked the position of the hinges on the floor. Thenn drilled one hinge and then used it to match drill the other hinges. I drilled the hinges at #40 size. Then I positioned and drilled the hinges to the floor with #40. Finally I enlarged all the holes to #30.
