I did one on a contender stock. What I did was cut a block of wood to the size of the butt stock and the recoil pad, keep in mind that there is a slight taper. I did have an advantage as i am used to working with wood, after i had the right fit I painted it flat black, remover the short recoil pad screws and replaced them with longer but same size and it worked well at least for me. You may find that your stock is hollow so you need to fit the wood block so it will fit inside your butt stock maybe a 1/4 inch to keep it in place.
