My replacement roy shoulders arrived today both of them were already broken in the bag making me a saaaad panda.
Edit. Ok, so all four of my roy shoulders are broken on the burred end of the pin. If anybody has a roy with intact shoulders (don't think it won't happen to you - it will) I seriously suggest you remove the pins and sand the burrs off. You can't count on your replacement parts being any good so the "if it breaks I'll just get a replacement" mindset isn't really effective in this case.
