2 sets of flanges
top flange - well ok
botton flange - this is the fun part
definitely a test of patience... but I guess
report back with video...

why, install another starnut after taking one out ??? (scooby-doo face)

rust? I don't see no rust - I see patina...

you could swab the patina with naval jelly and then swab with alky-hole to clean and then swap some nail polish on it
or
just install the stem and go ride...


oh, i forgetz, this is the 41...
