I live in Australia & I had exactly the same problem with a Moog lower control arm ball joint a couple of years ago on my 67 Impala.
It`s a manufacturing fault, contact them, they will replace it. There`s no way i`d be modifying anything to suit a faulty part.
If you compare the faulty one to the good one you have you`ll see that the faulty one has had the hole drilled in the incorrect position.
Unfortunately, as I suspected when I had this problem, most likely these are not made in the USA anymore but just packaged to appear that way.
