I need an accurate measurement of a 1/2 ton one to prove or disprove a thought I have.

Thanks in advance guys.

OK, the lower ball joint diameter is 1.975 inches, measured at the mounting area, ball joint tapers toward the top of the mount to aid in pressing it in I assume. Let me know if this is what you needed, or if you need another dimension.
