I can't find the link now, which makes me a liar.... but there's definitely a new butt pad assy you can buy. It replaces that fully adjustable LOP with a non adjustable for LOP one. It still allows the pad to move up and down using a screw. A lot of the excess material in the butt Assy is removed and makes the LOP 13.5".Did you ever figure this out? What video did you see it in?
