I would recommend welding it up with the pinion at 2-3 degrees (pointing up), and then adjust when the motor and trans are in. Typically the pinion angle should be between 2 to 5 degrees on the rear of trans (pointing down) and then the angle on the rear diff. pinion should be the same (but opposite) angle (pointing up). If you set it up at zero and have to adjust up to 5 degrees, the four link bracket where the shock mounts will be skewed and the shock will have unnecessary binding.
