I was getting organized and preparing to deburr the floors and baggage comparment floors and some how I realized I put the wrong nutplates on the forward attachment holes for the flap weldment braces. So out comes the 90 degree drill and I removed and replaced the K1000-8 with the proper K1000-3 nutplates (2). Then I deburred the holes for the floor boards and the baggage floors. Most of the time was spent removing the plastic.
