I have a new model single six 22, that was the first gun my father gave to me. Many moons ago I had to change grip frames. It currently has a SS super Blackhawk grip frame on it. I'm trying to order an original style aluminum grip frame from Ruger. I know the grip panels are different but do I need to get new screws, hammer spring and strut or will the current ones fit? I did the change over thirty years ago so I can't remember.
