I conected lock 6-C-4-1 and support 6-C-4-2 with an AN3-05A screw, 2 stainless washers UM0515 and stopnut AN3. 2 holes drilled through upper longeron, and flared. Use MS24694-53 screw with double washers and AN3 locknut. Next step was connecting lock and central lever with a stainless rod. I used AN3-05 bolt, one stainless washer and one AN960-3 locknut together witn AN3 locknut. The manual is not exactly clear in this area, but it's pretty obvious when you have studied the parts. All done up to page 22 in fuselage manual.
