My plan today is to get the rear/lower bag mounts tacked on the rear end housing. I have a few questions first and I am hoping for some advice from those who have done this.
I made 5" blocks and I have the flat part of the frame sitting on these to establish my desired ride height.
(1) When I square up and center the rear end, do I want the center of the axle tube centered in the notch at my 5" ride height or when it's fully aired out?
(2) At ride height does the pan hard bar need to be completely flat? In this pic, it is in the center holes on both sides so I have a ton of adjustment.

I also plan to mock up the engine and my empty transmission housing in the chassis to check driveline angles before I tack the lower bag mounts on. I'm hoping it's a productive day.
Thanks for any advice
