Hi John ,
Be shure I'm also a lover of original parts and I follow you completely.
Just wanted to help.
If you are in for buying buckets for the cage nuts only, as I said , they can be found on other Carello buckets, that I have checked in the Carello Catalogs.
But of course, I hope you can get them from the other member.
If not, PM me and I try to buy some buckets here in Europe for you.
Rgds from Belgium,
