I have adjusted mine to:
Front shaft down 2* to rear.
Rear shaft down 2* to rear.
Pinion yoke face 92*. ( facing up to front)
It still feels to me like it is binding a little when I first accelerate. I have never felt any real vibration either but I cannot seem to get rid of the feeling that the u-joints are bound up a little when I accelerate from a dead stop.
Measure the pinion face and see what you get.

I have a 2pc drive shaft and experience absolutely zero vibration, here are the drive shaft angles:
rear shaft @ differential yokes:
rear shaft @ carrier bearing yokes:
front shaft @ slip joint
front shaft @ transmission yokes
rear shaft @ differential yokes:
rear shaft @ carrier bearing yokes:
front shaft @ slip joint
front shaft @ transmission yokes

Nice to know, but there are a few factors left on the table when doing it that way.
The main one being how level the ground is that your vehicle is setting on.
That could throw a few of us off if it is not setting at a 0* level from the beginning.
I need to check mine as well. The 2" shackles only gave me a vibration from a standing start up until 20mph. That is only under any given acceleration.
Mines probably setting close to 2* at the driveshaft going into the pinion.
It looks almost level with the driveshaft now.
Hey Moregrip, are you using shackles and hangers??? I see the Caltracs! I like.
Either way, nice write up. Just very curious on how sure you are about the truck setting on level ground.

Cool, thanks. Just wanted to make sure! 
What about the shackles and hanger question??
Are you using any of them?
