Lots of little things getting each rib prepped. Added Nutplates to sloped sections on some ribs including one which also calls for an AN52510R10 screw and an MS21042-3 but it is REALLY tough to get the nut on. I'm suspecting that there was another mistake in the Van's shipment (other bags were wrong) that hasn't been caught yet and that the MS21042-3 aren't really that.
In one other section, you cut out the cutout of the doubler plate on the web of the rib (I forget which one). The drawing shows on large hole but the instruction to cut out the cuttout leaves a thin strip on the web. As there is a #12 hole nearby, I opted to leave the strip and take the instructions literally.
