We had a similar problem, due to the dummy spar not being exactly the same as
the
wing spars. We eventually tried a reamer, bad idea, too much slop when we went
back to check how much material was actually removed. We finally replaced all
the
bushings. You would only need to reset one in the cockpit module (assuming you
haven't reamed yet). Remove the plywood reinforcing, insert one of the 1/2"
bolts into one of the bushes, then heat the bolt with an industrial strength
heat
gun. Bond it back in with Redux, using both wings as a jig. That what we did.
