I had to be a little careful here keeping my perspective on where the notches had to be made on the HS-404 ribs. This had to be done in order to fit the ribs over the HS-710 and HS-714 reinforcing splice channels on the front spar. Both a right and a left version had to be made since they are not symmetrical.
