I'm helping a friend replace the outhaul line in the boom from an older J22. In the process I removed the vang bail and noticed the holes in the boom have become elongated to about half again the diameter of the hole. The threads of the vang bail bolt have "chewed" away at the holes. Replacing the boom is not an option for today.
A Use the existing holes.
B Drill new holes aft of the old holes about 3/4" back.
C Drill new holes 3/4" forward of the old holes.
