Moldboard plow

I was given an old Massey-Harris 3 bottom plow. Everything looks to be in good shape. I’m cleaning it up and gonna paint it up. I pulled the bottoms off and was wondering if the shares are still good or needs replacing. I never messed with them much. Leave em or replace em?

looks like the share is worn pretty bad
