With the center section riveted together for now the next thing is to add the seat floors and baggage compartment floors and drill all holes. For some reason Vans has you do this after the seat and baggage ribs are riveted to the bottom skin. I suspect the concern is that with only clecos there could be a tolerance issue. I did not get to drilling the F-715 ribs to the seat skin.
I also did one pickup item that I neglected previously. For some reason I missed drilling the bolt holes (top and bottom) in the forward flange of the seat ribs.
