Working on the horizontal stabilizer. Instructions for the spars and doublers said to "match drill" holes. For the ribs on the spars, the instructions say enlarge holes. Do these terms mean the same thing or do I disassemble all the clecoed parts and drill them separately? If drilled while clecoed together, do I need a longer drill bit? (Seems I wouldn't want to push the rib out of the way with the drill.
