Cut out lean wing truss shim and after assuring that no extra powder coat inside of mounting holes of truss, it was joined to the leading edge / d-spar. Also attached strut truss fittings to the truss, this requires match drilling those fittings to a particular location on the truss. Some question as to whether or not there is to be a washer added between the truss and the fittings, text calls for them but they are not shown in the diagrams. Email to aircraft tech sent.
