finally got the bump steer to near zero
After a lot of head scratching and brain ache and 2 trips and $200 to pedders with how to correct the problem of too much bump steer, finally came up with a solution. It did involve making a bump steer tester out of some waste steel a couple of guages and a piece of white laminate wood. This tool is invaluable and I would thouroughly recomend making one. 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.
