As long as you have to move the spring perches on the new axle pay attention to the angles. You can have the pinion angle dialed in on first pass. Don't just move the perches over without verifying the angeles. Plus my last 2cent tip is read all angle and distance yoke to yoke. Then reread angles after install. It's nice to have a baseline to work off of since you already got an assembly in the truck.
