				| Ah-ha! The length of the inboard J Stringer is discovered! (or implied)
 I looked at Drawing 11 and looked at the size of the rivets that go into the J Stringer. I noticed that 3 of the rivets are longer than all the others, which indicates that the metal must be thicker here. So this tells me that the length of the inboard J Stringer must go 3 rivets past where the skins overlap, as shown by the previous picture.
