Today, I fluted the bottom of both 814A R&L inborad seat ribs to line up the holes using a straight edge. I final drille dth nutplate rivet attach holes to #40 and machine countersnk them.
I made the 805D brackets, then clecoed the seat rib angles to their respective inboard seat ribs.
I then clecoed together the parts making up the seat belt anchors, 814HPPX times 2, and 814A R1 seat belt vent anchors. I did the same for the left seat belt anchor except using a 814PPHX, to replace one 814 HPPX, and clecoed each seat belt anchor to it's inborad seat belt rib assembly.
The 805D r & L brackets were clecoed the their inboard seat ribs and the second rivet hole required in each bracket was then drilled using the seat rib/angle as a template.
Lastly, I drilled all 1/8th holes to full size in the inboard seat ribs.
