There are many possible problems when you buy a kit from someone else .... So tonight I was checking the J stringers holes in the ribs F606, 607, 608, 610, 611, 612 against the drawing and realized there were incorrect holes position made in those ribs. So I remarked everything and have found a solution . But that takes time to read and analyse against original drawing and against the latest set of drawings I bought for reference. See some pictures below shows you some issue found (slots = holes)
