Are these calipers on correct?

If you elect to mount the calipers on the rear versus the front utilizing factory components from the later model 73 up mopars that were designed to mount on the front or forward position (1 o’clock position) does it require using the spindles from opposite sides? ( left spindle relos to right side and right to left).
Caliper mounts only one way to spindle so yes spindle with caliper mount and caliper get switched left for right. Steering arm is formed on lower ball joint so those stay where they were, right and left.
