In response to BBLemond
I needed a spot on each side of the rearend to measure from so I took the plumb bob and strung it around the axle flange. I figured that it wouldnt matter how the rearend was rotated since it should be perfectly round there.
I measured the distance from each side of the rearend to the center point and adjusted the rearend position accordingly. The first adjustment I made was to get the lower arms the same length. Im not quite sure how I got that wrong but I guess thats why I went through this alignment process
Adjusting the rearend side to side with the upper arms attached was impossible so I removed both uppers and got it centered. Then I set my pinion angle with a floor jack and reattached the upper arms. I made sure the bolts slid into the rearend bushings easily so they wouldnt cause the rearend to get misaligned. Having the upper arms off for this part made it go much faster but once its all assembled having the Chassisworks double adjustable arms will make it much easier to adjust the pinion angle in the car if I need to make small adjustments. I will just have to adjust each arm a little bit at a time and go back and forth so they are adjusted the same amount
For the pinion angle I set the rearend almost exactly the same but opposite as the transmission. If I had leaf springs I would have set it a degree or two down but I don’t think the pinion should change much or at all under acceleration with this suspension configuration.
