Mike -
your best bet is to follow ALL the online auctions closely, and haunt your local gunshows, toy stores, and pawn shops.
you just never know where anything will turn up!

I offer both commiseration and puzzlement - it seems few 'smiths are willing to tackle this , even tho it seems simple enough.
the parts are called eith "firing pin bushings" or "recoil plates" and sell for between $13 and $35 depending on make and vendor.
I did finally find a photo:
this thread discusses it:
http://www.cascity.com/forumhall/index.php?topic=38363.0http://www.cascity.com/forumhall/index.php?topic=25491.0depending upon brand, one may just be able to "drive out" the old one and "glue in" a new one.
If one needs to mill a new bushing hole in the frame, removing the barrel and milling a hole ~ 3/8 diam and .1 deep does not
seem
overly difficult - easier than milling and threading holes for a floating firing pin and its threaded bushing, which I am doing
for 2 remington 1858 thick plate conversions ....
but hey I am not a gunsmith, so what do I know.... and I am retired now and my time doesn't cost anything
( unless you want computer help - then it's $250 per hour. more if I don't like you )yhs
