Pinion angle question.

The nose of the pinion is pointed down exactly like the drawing. That’s what had kept running me for a loop earlier is every online calculator etc. says it’s “up” when the NOSE is down. They start and the very front of the car and keep working back, hard to explain, but anyway. So yeah, all my angles are as I have drawn on the paper

Ok got it. Not trying to be critical just wanted to clarify because of pinion arrow going up.
I would try a 1-2 degree shim to roll pinion up.
This sets your pinion at -1 to 0 degrees resting angle.
With your trans down at 2.4 degrees.
Pinion is now at a 3.4 to 2.4 degree differential/lower than trans angle.
So depending on your springs when power is applied it should roll up so pinion angle and trans angles are parallel. Not in line but parallel.
Again try rolling pinion up 1-2 degrees.
