This topic can turn into a real can of worms so be ready.
The pinion angle should not be adjusted with full weight of the truck on the springs with the truck on the ground in " as driven condition " .
The pinion should be close to parallel to the crankshaft
The u-joints should have a working angle of more then 1 to 3 or less degrees ideally, but more or less will still work. .
3 degrees is a standard starting point, but not set in stone. Lots of 4x4s have drastic angle drivelines, and lots of cars came with very little angle
Long leaf spring can twist under heavy loads, so adjust for that with more pinion angle if this is working truck ( when twisted under load, the pinion would be in the correct position ) 1 more then crankshaft
