Driveline angles
I'm chasing a vibration issue in my '64, and I'm trying to find the original C2 specs for driveline angles. From what I've read parallel U-joint angles are ideal, but maybe this isn't the case with this setup. Or maybe I can't get there from here.
Right now the rear trans yoke is at 2.75 degrees tail down. The diff yoke is 1.45 degrees nose down. I think it needs to be nose up at close to the 2.75 degrees of the trans yoke, but then I've also read 0 degrees on the diff yoke is correct.
All the u-joints are fresh, drive shaft is straight and balanced. Diff has about 3K miles from complete rebuild.
Thanks for any comments.

Passenger cars should be in the 2* to 3* range I would think you need to adjust the differential....be very careful how you measure things; its easy to misread the angles.
I don't know where the 0* came from, U-joints are designed to operate at an angle.
Here is a good article on chasing vibrations:

Parallel but in OPPOSITE planes.
