Hi All!

I have a 1927 A1. I'm trying to figure out how to replace the extractor. I can't figure out how to get it into the slot in the bolt. It seems like it's too tight to fit. It goes about 1/8-1/4" into the slot but won't go further. Does it need to be tapped? Also, does the end need to be lifted a little to get over the end of the bolt?
I haven't been able to find any instructions on how to replace it.

Thanks.
