tightening uca ball joint/delta joint nut with gusseted spindles

replaced my spindles this weekend and tightening the nut with the gusseted spindles especially on the driver's side was ... challenging. not planning to do this again in the near future but it's bugging me that i couldn't figure this out. hoping for the tw jedi masters to teach me the secret to this.

 

Righty tighty, lefty loosie?

 

What he's asking is, what are people's procedure in tightening down the uca to spindle bolt when there's barely enough room to fit a wrench on it, when the spindles are gussetted. To make matters worse, he is asking also because there is no bolt head on the ball joint type uca's to turn while being able to just fit a wrench on the nut below, that can barely clear because of the gussets.
