Wow didn't see that coming!! The extractor will fit. Do NOT change the ring.
You did OK keeping that Lyman 48. They are not all that rare; they made a bunch of them. The StaySet knob version you have is a much better choice for a hunting rifle, but most people prefer the looks and/or ease of adjustment of the target knobs.
Your Lyman 6 is a simple sight as is the 6W; they are rare hence the high price. You showed what they cost new. Lyman 48's are a much more complicated piece of machinery and cost a good deal more when new, but the 6W will bring more than a nice 48 because of the rare factor.
Read and ignore my previous PM's as that is water under the bridge. I kind of thought you may have cancelled the listing to keep for yourself. That Lyman deserves a nice low comb 375 H&H or a high or low combed scoped up model in any caliber, perhaps one with a G&H sidemount.
I have your extractor's twin, but could have bought 4 for that money there. I should probably put this in a PM, but want to make sure you see this: If you think you need to replace that bolt for any other reason than excess headspace, you probably ought to sell that pre 64 and buy a new gun with a warranty. Vintage guns like pre 64 70's were bought to be used back in the day, and they were used. The cleaner unused or slightly used go for over $1,000.00 - well over $1,000.00
If the gun has good headspace that bolt is fine, not perfect, but will work just fine and last a long time.
Well those are my opinions anyway. And you know about opinions, they are like something else that everyone has and everybody else's stinks worse than mine. Good luck.
