Fit Forward half of F704 bulkhead to mid fuselage assembly. Applied Side stiffeners and checked spacing for wing spar which was good w/n +/- 0.003. Since all holes are pre-punched, I did not see the need to install the wood block shims where the spars would go. All holes aligned well. Drilled holes out to final size, including the countersinking of 4 holes called out on the bottom skin & F704 forward intersection.
