I need a magazine follower and spring for one. Would anyone other small action parts work? I was thinking Zastava mini mauser but can’t find those either.

Possibly an old Sako L461 if you can find one.

The L461 worked in a Zastava mini so maybe a Mini will work in a Kimber

So far no luck with a spring. Found a used Zastava M85 mini follower. Zastava usa says they carry them but they are out of stock.

Long shot: Cooper Firearms

At the parts auction in Colton, OR, Dan Cooper bought most of the parts. I was able to buy some 82 parts from them LONG ago. I passed this information on to someone "recently" and when they got ahold of Cooper they had no 82 parts left. I don't know if they had/have 84 parts.

I can measure the follower on my KoO M84 223 if that would be helpful.
