    Bushing the fitting was my suggestion to the Cub Crafters engineers but several months later they chose the other route. Seen Super Cubs run through trees and the fitting faired well but not the fork.

    Given the amount of material around the hole in the fitting, there wouldn't be a problem. Using a bushing actually increases the bearing area on the fitting. The forks on the other hand don't have quite as much edge distance (but they are a little thicker, and in double shear).
