Well I finally got it all back together today. Here is a pic of the actuator arm I created. I built it out of three pieces of aluminum and welded them together with alumiweld. Amazing stuff... Anyway arm worked and you can do this repair without removing the IHKA. I could make this arm for other members but it takes about 3 hours of machining and welding, so it won't be cheap . Also found out why the flap broke. The stepper motor was pulling to far so installed a shim between the stepper motor arm and the stop. I also reinforced the mounting bracket with JB Weld, filled in all the holes and then wrapped it with parafilm until it set up.
