See my post: http://www.vansairforce.com/community/showthread.php?t=153840&highlight=handle.
Go to page 29iS/U-10 and 11 in the KAI for drawings and parts list. I just ordered the parts for possible installation during my CI in June/July. I will try to remember to post results.
The two optional autopilot knob panels for the legacy 12 get in the way.
I purchased the egress handle parts last year and am still trying to figure a way to make the work. No joy so far, but I have not given up.
I have a legacy 12.
