Ball joint and plate fit perfectly but the top lock nut did not fit on the ball joint stud. The bolt is 14mm metric thread and the nut I received was a 1/2" x 30 thread. I had to have a friend drive me across town to find a nut for it. Advance Auto, O'Rileys, Lowe's and Home Depot couldn't find anything suitable Eventually I found a nut at my local hardware store Maybe it was an assembly error but with any other seller it would be safer to try someone else .
