Sorry you did not get an answer but the 7 as well as the 9, and all others are on the Internet with a Google search. When you need info on about anything try an Internet search.
I just did a complicated trigger, hammer and sear replacement for a Ruger Mark IV 22-45 pistol by searching for and finding several YouTube videos on that particular task. Not a day goes by that I do not research something on the Internet and find multiple answers.
