installed SS springs and pinion angle is at 0

According to the Mopar Performance chassis book on page 252, the trans to driveshaft angle should always be 2.5 degrees or less (but not zero). On page 253 all the pictures showing how to adjust rear pinion angle show only the rear axle pinion and the driveshaft. No trans pictured or any reference to it for the rear pinion angle adjustment. And the chart says 5-10 degrees nose down (5-7 preferred) for a leaf spring setup. There are other measurements if ladder bars or 4 link is used.
