Drilled EF-606 bracket to EF-601. Drilled 1/4'' bolt holes thru EF-601 and EF-606, Made spacers. Found that I missed the note in the electric flaps instructions about trimming the EF-606 bracket width from 1'' to 3/4''. Because I did not do this, the bolt is too long. I now need to use an AN4-16 bolt and add two washers.
