driveshaft angles

That's true, it does. What it does not show however, is how the suspension loads and changes the u joint working angles. Without that added into the equation, you cannot set the angle correctly. Every bit of this is covered in the MP chassis and suspension manual. I just don't get why some people (not you) want to say their methods are incorrect, because they are not. They're spot on.
When you set your pinion at 5 deg. what was the angle at the crankshaft centerline?
