Dolly scraper trunnion ball?

[Cummins5.9]

I’m trying to find some part for a project I was working on and can’t seem to locate what I’m looking for.

im looking for the ball and socket that would be on a cat 80 size scraper and dolly set up where the gooseneck would attach to the dolly.

would anyone have any idea on where I may find something similar?

thanks

A friend of mine has a cat 80 and needed a couple things for it. He found a guy in South Dakota that had quite a few of these scrapers. Maybe someone on here knows who I'm talking about?? Otherwise I can try to get his info and let you know.

Even if anyone knows round about dimensions of the ball like if it’s a 6 inch ball or what
