1973 Plymouth Duster repair and rebuild

Well, it MIGHT be correct for "whatever" application it WAS in. Not everything is automatically 5 degrees down. Most older Mopar applications are. Again, you may be confusing pinion angle with U-joint working angle. In other words, have you actually MEASURED the relationship between the spring perches and pinion centerline? You cannot just "climb under" and measure it static on the vehicle, since the spring perches are probably not plumb and level. Understand?

I can not. My drive way slopes down hill quite a bit. The rear tires have blocks preventing it from rolling down hill while the front end is on Jack Stands under the K Frame and A pillars. I was trying to be pro active. Figured set the pinion angle using my digital angle finder and set the perches to 0 degrees. Then weld. That sounded easy enough. And would minimize the time the rear end is up with less safety issues on the hill. More so, since I am not on flat ground, I dont want the car way up in the air. Up high enough to get the axle in, then get the car back on the ground.
