Drop Spindles - PST vs. Magnum Force vs. Fatman vs. ?

I bought the magnum units. They are for my 1964 Australian valiant same as dart really.
The lower ball joint arms are longer than the originals on the car. I had been running the later vented disks. The car had been off the road for a long time and prior to pulling it off the road I had no issues. I'm not sure of the longer arms which will push the outer tie rods, out of alignment with the drag link and pitman arm. This should be kept in a straight line from one side yo the other. However I cannot fault the spindles in regards to their appearance. There is a lot of thick chunky metal and they don't look like they would fail in a hurry. I guess time will tell when I get her finished.
