Wish I had read this post earlier, I would have pointed out the butt pad is a custom fit part which you would've wanted to keep intact.
You can fit a new one by using a jig or the" enthusiastic amateur " way by scribing the back of a new one and using a belt sander to slowly sand your stocks profile, the pads are designed to be sanded It sounds hard but it's not just time consuming, it'll look better too.
Of course you'll have to address the striped holes which is simple.
