Finished fabricating the spacers and then clamped the spacer, the 906A angle I fabricated along with the 906B plate and drilled everything. Did that for both flaps. Then put the bottom skin on the table and drilled the rib holes into the table. Removed the skin, and drilled the 5/8th holes for the cleco's to fit into later. Then match drilled the ribs to the spar. Cleco'd the bottom skin to the ribs and flipped the thing over to see how my holes lined up. Good. Next, I'll match drill the bottom skin to the ribs.
