Flange to pinion angle?

[Quickboat]

I was getting angle measurments from my original 10 bolt to transfer to the welding of my new 12 bolt. I noticed that the axle flange (where the brakes bolt up) was clocked at approx. 7 degrees to the pinion and the spring perches were clocked at around 3 degrees to the pinion. Why are these so different and does it matter when welding on the new "Torino" axle flanges and the upper/lower brackets for a 4-link system?

What 4-link are you installing? The reason I ask is because my Chassisworks GLink came with a fixture to hold the mount brackets in position while they are welded to the housing. Use of the fixture ensures the correct location of the brackets. The pinion angle is then adjusted with the link bars in the car at ride height. Where the axle flanges are clocked is not critical within reason but they should be the same side to side.

I am using he RideTech triangulated 4 link. They were not specific about bracket placement only telling me not to "over think it" and to weld it perpendicular to the housing ends. I'm an engineer by trade so I always over think it! But to weld in lower bracket 90 degrees from the housing ends would place them 7 degrees off pinion. I think 3 degrees would be closer for the lower bracket and the 7 degrees for the housing ends as are the stock 10 bolt ends.
