Tuned up the outer L-angles (the ones that rivet to the skin) so they have the same shape. Pilot drilled cross brace line in the floor. Finished drilled front and rear baggage floor rivet lines.
Refit baggage floor and marked end holes for the line along the outer skin. Back drilled the end holes.
Had to remake the left upright because the flange was to short for where the verticle rivet line is going.
