When I installed the ribs last week, the plan called for K-374 to be installed at rib#12 position. K-374 is facing inboard. On the same page it is indicated to put all the ribs except rib#11 facing outboard. Also on some other builders website, I saw one facing inboard and another facing outboard. So, I decided to go with K-374, as indicated, which is facing inboard. No big difference except to attach the 3 heavy duty stringers that goes under the fuel tank. I want those stringer to be attached strongly on rib#12, so I bent the end to be able to put 3 rivets in it.
Finally, I ran out of rivets 412. I'll have to wait to finish the bottom stringers.
