Swaybar end link.. nut on spring perch…. Size?

[cblfhs]

Working on getting my swaybar back on the jeep to prevent all of the body roll. The nut; the nut on the swaybar system that is closest to the floor. It’s also the largest nut in the system. There is a bolt that’s coming off of the spring perch…. What is the size of that bolt/what is the size of the nuts that I am missing that screw on to that bolt which hold the bottom most part of the sway bar end links on?

I want to say it’s that nut

Off the top of my head think it is 1/2" x 20 thread. Seem to remember that was the die size to clean the ends up. I can check to confirm.
