maybe too much powder coat...? 

Too much powder coating is a common problem for all powder coated parts.  Scrape the inside of the hole clean, I'd say.  It's almost, or maybe it is, an interference fit.  Zero play.

BTW......Cotter pins were added later?

I always buy the MOOG ball joints. Never had a fitment problem underneath with the ball joint not fitting through the control arm hole. After you clean the powder coat off, make sure it fits completely through without interference, don't tighten the bolts bring it flat.

I use MOOG as well.

same here

@Tirnipgreen did you ever sort this one out? I have just run into the same thing with the flange on the new ball joint not sitting flat to the LCA
