A neighbor happened across a bag full of brand new two piece dies, Greenfield Little Giant brand. They are about an inch square (each half) by maybe 3/8 thick. I've looked on eBay but I'm not sure what you would need for a die stock and was wondering if you need a different round plate for each thread size? I'm sure someone on here knows all about these. I guess I'm asking what I need to buy to make use of these.
