I agree with the above statements, the threads as they near the cotter pin hole don't look proper. Also looks like the top has been worked with a file or smacked pretty hard. Take the 2 bolts for the spindle out and drop the ball joint back out to look at it. If it's been hit hard likely to deform because of the cotter pin hole. Also , your stuff dirty for reassembly, or are those filings?. A squirt from a can of brake clean will clean things up. A lower ball joint is not something to take a chance on. If it's questionable at all,get another one. As said the nut should thread all the way down by hand.How ypou going to hold it to run a die down it? Do not score up the tapered seat.

Muu Muu 1) Disassemble what you have done till the spindle can be moved to the workbench. 2) See if a file will clean up the threads so that you can spin the nut either by hand or with a small amount of resistance. If not replace the LBJ. 3) After you have it working or have replaced the LBJ, install the LBJ through the LCA. Make sure the slot for the cotter pin is facing front to back. 4) Put a small floor jack under the spindle so the taper is seated in the LCA and tighten it down and install the cotter pin. Access with a wrench and a rachet will be 10x better. 5) Install the UCA down over the spindle. Again, make sure the cotter pin slot goes front to rear and tighten. Aligning the cotter pin slots seems like extra work but if you ever have to fool with it again you'll be glad you did it. 
...FAFO...

The stud is bent, You can try chasing the threads but you risk cutting material from the threads on a key suspension part.
I would just purchase a new balljoint, why compromise something so important. It's 10 minutes extra work to change it out, but now is the time to do it.
Just put a centre punch in the middle of the top of the stud and give it a light tap with even a carpenters hammer, it will loosen it.

I can't see how you could for sure say it's bent from those pictures. I see a thread second from the top on the left side that looks a little dinged. He might be able to work the nut back and forth by hand to straighten that.
BTW the threads near the cotter pin are commonly chamfered in a little. No big deal. And because he took the picture pure perpendicular to the cotter pin centerline, it looks like it's necked in there.

 I takes a lot to bend a ball joint stud and that one doesn't look bent. But the threads need fixing to where you can run the nut down by hand and then tighten it with a wrench.
I was just going to say, where is everyone seeing the bend because from that picture I don't see much of any a bend and I just took a quick look at it from under my car and it looks straight. I will agree that the threads look "smashed" by the cotter pins (not shown in the picture). The nut only went down about two full threads. I'll pull the LCA balljoint off, get a die, and try running the threads hopefully by or before next weekend.

You shouldn't need to take it off to run the die on it. Just do it were it is.

I might have a die around...what thread is it? 
No idea... I don't have a thread gauge.

Lovely, exactly what I wanted to do, take apart half the entire front suspension just to fix a new part. I'll buy a tap and die set next weekend and work on it. Is there an "easy" way to unseat the LCA and UCA ball joints from the spindle without using a pickle fork? And for the record, I did not hammer or file these ball joints.
If the stud is spinning in the LCA, the ball joint isn't set. Back off the torsion bar completely, jack the LCA up and the ball joint should just drop out. Then you can remove the lower ball joint, stick it in your vise, and work on it without fighting anything.
I already set the LCA in the ball joint to get the nut out and the Torsion bars are already backed off completely.
