Trim tab hinge holes countersunk to much on tab side . used 3.0 oops rivets , same size head, they worked pretty good after cotting to length. All 15 of them P.I.A. Inside and outside dimensions to spec. sort of . Had to lightly grind a blind rivet head on inside tab. My trailing edge of the trim tab protrudes 1 or2/32 past the trailing edge of left elevator , looks fine to me.
