I am repairing my PA-22 rudder.
I am looking at drawing 40622X -- rib uncovered. (this is the elliptical rudder- not the older triangular cub type)

The drawing shows the part numbers for the 4 trailing ribs but there is no part # for the
forward rib. There is an arrow pointing to it that says "see table" --- but there is no table
on this drawing. (appears that "table" was removed from the drawing at some point previously-
per the red "X" in the drawing # )

Anyone happen to know the part # for that rib ? (or a hint how to figure it out ?)

Thank you ahead of time for any thoughts .......
