Also note that the new kingpin kits are made to long. The top of the 
kingpin will hit the shock arms when you lift the car. So you need to 
cut off the top non threaded section to allow the suspension to move 
correctly.

This has been an issue for about 10 plus years. And after telling the 
various suppliers about the problem many times i just gave up and fix it 
when ever we rebuild a suspension.
