I would put all the inch worm rebuild stuff in and or , marlin rebuild stuff or see who has a box of stuff from rebuilding dule case. Mabe cheaper but
Once you get that case apart you will see , it's real easy and open marlins page for the 4.7 and go along with it. Good luck. Ask for questions if you need to
I'll check you out soon
