Nevermind, lets just do it all the same way.

How do you check bump steer with an angle finder? we allways unload the torsion bar, and set up a dial indicator system on the hub, and run it up and down throughout the suspension travel, checking for toe change during compression and rebound....

That's a good question, but you have to admit that this will eliminate most of it. You are removing 10 degrees of angle from the tie rod setup. I'm sure that it is not as precise as your method, but will give you an idea. I'm sure that there will still be a little bump steer, but nothing compared to the factory setup. My display in the pictures is level.
