My 7 drawings show W-709 leading edge rib and W-712 as the aft outboard rib. There is a L and R for these based on the flange direction. The left wing is R and right wing L
Not sure what the discrepancy is. I just looked at my -7 plans and they show 3 "outboard ribs W-712" on each wing and the -R and -L refers to the direction of the flange.
