factory 1969 12 bolt pinion angle

[mark x22]

I redrew the spring in post 10 . When you set it up just get the 6 degree difference between the pinion and the spring perch as shown in the first drawing . Don't worry about the ground or the car that could vary with ride height . Just make it look like the drawing .

Thank you all for your input!  It makes sense to me now.  Even though the perches are welded on the axle tubes at a pinion angle of 6 degrees up, when the rear end is on the springs and installed, it is closer to neutral or 0 degrees.  That last drawing was excellent.  Does the assembly manual show all of this?  I better get me one.  Thanks for saving me tons of time and a headache later on.
