Drill out the holes in the forward seat floors and prepare. Dimpled the platenut holes. I trimmed a very small amount off the outside edge of each seat floor so it fitted easier. Fabricated the F-741-A tunnel cover, cut, filed and smoothed the Z brackets and screwed them in position. Next was to mark and drill the holes in the top plate and then held the plate in position and back drilled the rivet holes in the Z brackets. Remove, debur holes and countersink the bracketrs to accomodate the AN426AD4-5 rivets. I decided to give this the full corrosion treatment and prime as well, rivetet together. Primed the seat floors and riveted on the platenuts.
