Place to procure remington part

[DumduminMud]

Generally, the rivot and ejector pin for wingmaster 870 model.
Was trying to get it converted to magnum (from 2-3/4 to 3; local gun smith is willing to do it); however there seems to be a parts epidemic and thus the parts cannot be acquired lol
specifically, i need part 17, 18, 19, 20,(ejector assembly), 47(the bolt); possibly looking for part 21, 22, 23 (extractor assembly on bolt) as well.
I have called remington (remarms, not remington homecare.) and the feedback was "go to agency gravel", whom has been missing a shipment of parts since february and possibly earlier.
So I think it doesn't hurt to try here.
Cheers,

17.18.19.20 are in stock and available from forum businesses. You probably can’t find em all in one spot but you can find em. Ones on the EE or gunp*st are overpriced

Extractor buy a volquartsen one if you can’t find a factory one. I’m sure someone on here would give you a mim one. Extractor spring and pin idk

47 gets swapped out when putting on a sage stock or the factory mcs dovetail or the one sj hardware sells. They almost seem like tapered pipe thread, not sure why people take em out.
