Ball joint socket size and where to purchase?

I wasn't trying to imply you said that. I'm just stating my experience with them. That's why I think there is a smaller one than the 1 59/64.
I'm still waiting for a dimension of the Proto Tool socket. As I mentioned it would've been nice for Mancini to list socket size lol.
I did not say they were the best. But they worked for the few sets of UCA I’ve done and the few sets friends have done, so for the 50 bucks or whatever I paid, they paid for themselves.
