Update: I finally have the part I needed. Williams Gunsight was great!!!! After calling late last week, a gunsmith called me back early this week, walked thru my needs, and handled it. My safe queen is back whole and my daily carry has its own parts again.
It all came together this week, to make it even better I was able to purchased another R9 of the same vintage as my orginal....it's been a good week. I really appreciate Williams Gunsight's friendliness and effort.
Thanks to JoshA, DDGator, and everyone for your help!
