The HRII tail conversion consists of one drawing, for the VS and rudder.

There are minor changes to the control surface leading edge rolling to make the "D" cell, but the biggest difference you'll find is that the lower leading edge rib (VS-405) is angled upward to clear the Rocket turtledeck. 2" is the amount it is raised at the leading edge.

YMMV. Order a set from John for the complete picture!
