I heard from the legendary Tony Kirk at Van's and he suggested using a long file to remove some of the trailing edge on the right side of vertical stabilizer where t is coming into contact with the rudder at full deflection. So I marked off about .048, made a straight line and filed back to it. No more contacting the rudder. Tony is the best.
I remade the tape strips to mark the attach holes for the empennage fairng and then dug out the two fairings. One step calls for you to drill a 3/4 hole with a step drill, 1 1/2" from a reference line. But then I remembered - vaguely - some dispute about hole callout on this part. I check plans and, sure enough, the latest plans have it 1 1/8" from the line.
I checked back with Tony at support to be sure threre's no issue with having pre12-iiS tailfeathers with a 12iS fuselage where this part is concerned.
BTW there's a service bulletin out regarding the radiator and cowling. The fix kit shipped today.
