well i shipped the passanger side knuckle out a week ago and got a message from the guy today that he couldn't machine the knuckle because it was bowed at the spindle mounting surface, and that is where his jig bolts to the knuckle. So it wouldn't sit flat on the jig and so wouldn't be machined flat. I had it shipped back to see if its salvagable. Here is an attached image, what is the general consensus. i don't know if the gap is 1/16" or 1/2" because there is no scale.
