We matchdrilled the top forward skin to the fuselage just aft of the cockpit. Doing this required drawing a centerline down each of the two top J-channel stringers. Once the skins were cleco'd onto the fuselage's existing rivet holes, we match-drilled through the existing skin holes into the J-channels. Everything fits!
We then removed the skin to prep for dimpling, etc. However.....
