    Default mystery part # for rudder rib

    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 .......

    Univair finally found the part # for the forward rudder rib. They Mfg. a complete rudder that they sell---
    Their blueprint apparently missing the part # as well--- but they had someone in the Fab shop that knew which rib that one was--- it is 40562-021
