what size/thread for steering box?

[thixon]

What size/thread is the splined shaft on the steering box (the one the drag link connects to). SPO tore up the end, and I couldn't get the nut on last night. I'm traveling today, and just remembered I need to pick up a a tap/die to clean up the nut and fix the threads on the shaft. Thanks in advance.

Sorry, I should have said drop arm, not drag link. Anyway, I'm looking for the size/thread for this nut.

Travis,
Using a rule I make it 3/4-16.
