Interesting. I pulled my whole lock assy off a while back ago to do restro but I never had those two parts on my lock assembly and it fits and works perfertly. Hell, I don't even have item number 2 on mine. My tail panel is flat and the bird sits flush with it. I am wondering if something change somewhere in 69 as I have a very early 69 (Nov or Dec 68) and thinking maybe they changed it after that? Sorry I cant be of more help then that.
