I could not use rivets to fastenthe outboard sub-panels (F-7105B L&R) to the F-902 (L&R) bulkhead due to extremely tight quarters. I was afraid to damage the bulhead. I decided to enlarge the 8 rivet holes (4 on each side) to #28 and use AN526-6R6 screws, AN365-632 nuts and AN960-6L washers. Although timeconsuming it turned out OK.
