The horizontal stabilizer front spar came off the shelf to match drill a couple of holes into the modified nose rib aft flanges and a hole in the modified in-spar ribs forward flange. I had not worked with the HS spars in awhile, so I was glad that I had marked the top flange and direction. That made orienting the spar to the ribs quick and reduced the chance of inadvertently doing things upside down! I wrapped up this section by dimpling most of the #40 holes in the nose and in-spar ribs.
