Carfully marked on the skin per plans where the diffrent rivets go, then riveted. I still put 5 Avex rivets where AAPQs are called out c/t to rear spar and foot plate. Drilled those out and replace with the correct -43 grip AAPQ's. The rivets c/t the foot plate skins and ribs are called out as -43 grip I used -42 which is corret by grip gage. Finally finished (except for the tip) this wing!
