14-Bolt axle into 67-72 leaf: Shock Brackets

[RPOZ11]

14-Bolt axle into 67-72 leaf: Shock Brackets:

As a novice welder and unsure of my direction on this, how can I determine the correct location for the axle housing shock mounts for replacement brackets.
I was looking at my Eaton in my Longhorn (my only axle to compare with) and was looking at the centerline of the axle/pinion/flange end locations and it must be based upon these angles; as well as the upper shock mounts direction from the frame.
What have you folks encountered, decided, and determined is a correct fix on this?
I am having my 14-Bolt rebuilt, and will need to recolve this once mounted....
Thoughts...
