The key is getting the pivot point of the lower control arm as close as inline with the ball in the steering arm on the rack, and the ball in tie rod end level with the lower ball in the ball joint. This should ensure the steering arm is parrallel with the lower control arm therefore eliminating any bump steer.
I had to bend the cast steel stub axel 25 mm upwards to raise the connection point of the tie rod end.
Finally after just over a year now ready to put the body on and make some real progress.

Damo...Did I read this right. You bent the cast steel arm that is connected to the stub axle. OOOh this is not a good move. The better way would to be to relocate the steering rack or box. Bending cast stuff is a very scary issue. It changes metal strength properties. The suspension bloke should have known about this. Pedders in Newcastle sold me a set of springs that made the car sit on the ground......no knowledge of spring technology just selling what they have. Please re think the bending issue.
