Ken,
The question was one of adding adjustability. By using the TR4-6 upper arms,
the TR4 trunion and the aforementioned Jag ball joint, you gain castor
adjustability. The ball joint in narrower (front to rear) than the TR piece, so
judicious use of shims will allow you to "move" the BJ forward or back to suit
your needs.
