OK, so I saw a pic of your 14 bolt on page 1 with the perches not on, so yeah just install your SYE and CV shaft and set the truck down on its weight and measure/adjust the pinion slightly (1-2 degrees) below the drop of the driveshaft tube. And burn the perches on. Use your angle finder on the flat of the diff yoke when it is the position its sitting how it is in those last few pics you posted.
