Thanks guys. I appreciate the feedback. Part of the problem I'm having is so many people refer to the angles in different terms. Not only that but people insist that the nose of the diff should be facing down. So that hopefully I can learn something from this, let me say what I'm thinking in terms that I understand. Please tell me if this makes sense and is correct of not.
The idea is for the trans and diff to be in a parallel plane when under load/power. Because I'm a leaf spring car, the diff needs to be 2-3* down relative to this parallel plane when the car is simply sitting on the cribbing. In this case, I'm 3* down on the trans so I need to be at 0 to1* up on the pinion which is 2-3* down from the parallel plane. Is this correct?
What about the drive shaft's angle? I measured the height of the trans and the diff in the car. The diff is only slightly lower than the trans, less than an inch. Does it matter that the drive shaft will be basically level while in the car, or is it strictly the angles between the trans and drive shaft and diff and drive shaft that matters?
Thanks
