I have some moldboards on hand, I think 2 of 14" and 1 of 16", Super Chief I think. Also 3 new shares.
I also have a one bottom IH plow and am thinking of pulling that moldboard (16"?) off and scraping the plow as it's left axle is bent and makes serious "toe in". All these parts are in really good condition.
I'm in Wisconsin, maybe that's too far for you to take a look? I'd need your phone number so we can go over details if interested.
