Thanks, I will also try neednose pliers. My fingers just won't cut it.

I just added one to my YS91 for the first time,for me. You have to position it so that it will go down and then twist and it locks. It takes some finesse and with my fingers I gave up. I had a small pair of needle nose pliers and held on to it, gently turned it until it was going down then pushed on tightly and twisted. It stayed!
