My caliper body hits on the knob on the axle just to the left of the grease zirk in the above photo.
Solutions:
1. Don’t worry about it because it will not likely cause a problem.
2. Remove the “knob” on the axle. ( not sure of the “knobs” purpose )
3. Modify the steerng stops by relocating the mounting hole, make them larger or add material to the spindle where the stop lands.
