From aligned Y fittings, upper & lower attach tabs, tailwheel attachment, all but two #40 holes were drilled and reamed to 3/8". The fit of remade upper tab was unsatisfactory. Remade upper tab XNB-F23-02 and bent to 94 degrees.
Will fit XNB-F23-02 to the #40 holes in the tail cone, then mark and drill to 3/8" on the Y fitting/channel stack.
Lower attach tab hole a bit too close to the angle web. Filed a washer edge to permit flat fit of bolt head.
