Forgot to mention, you will need a new extractor and ejector. Both are spring loaded so assemble in a plastic baggy so the parts doent go flying around the room. There is a spring with a ball on it under the extractor and the ejector pin is also spring loaded and held in with a cross pin you can push out. I think the ejector pin and spring can be reused as is the small ball and spring under theextractor in the bolt head you have. Best to have extras. Just push the extractor to the outside to remove it. Ball and spring will fly if your not carefull.
