Savage 1907 Extractor Replacement?

I've got a military contract Savage 1907 that's got some ejector issues. The ejector claw is a bit deformed, and it refuses to do it's job most of the time. I've secured a replacement, but now I've got the wonderful task of installing the damn thing... Is anyone aware of a video / tutorial / guide / whatever showing how to do this? Most everything on Youtube doesn't get much further than wincing at the complexity of the breech plug.

(Note: This isn't the same one I posted a couple of months ago. I lucked into a second one.)

I posted a thread on the complete assembly of a Model 1915 some years ago, back when photobucket worked, the extractors are the same but the video on changing them no longer works due to the changes by photobucket , It's one of the stickies at the top of this forum. If I remember correctly - to remove the old one, take a very small screwdriver and pry the spring back, the extractor will come out the side. To install the new one, just push it back against the spring until it can snap into place.
