F150 TTB Coil Spring Stud Nut Size?

Gentlemen,

Would anybody happen to know the thread size/pitch of the stud in top of the 4x4 beams where the coil spring seats are attached? I need to make sure I have a couple of these hex nuts on hand, and curious what size they are.

It is 5/8-11. And it is part # 388833-S, as shown below. But I confirmed that in the Standard & Utility Parts Catalog awa running a 5/8-11 nut on the stud on Dad's truck.
