[In MR.Pbodies car, he built his engine/tranny driveline paralell to the pinion. He and anyone else who does the same can accurately set the pinion angle off the Shaft.
People with Unmolested drivetrains can set the pinion angle off the shaft and still not have problems. Though the accuracy of the true pinion angle wont be known. As long as your getting a negative angle reading between the two of 3* to 5* or so. The U joints will do thier job and you wont notice anything most likely.
With a modified car such as yours, I think one can see you wouldnt want to measure it off the Shaft.
Your current measurements between the shaft and pinion give you a neg/-14*
Your current measurements between the tranny centerline and pinion give you a neg/-9*
""
Both sets of numbers are telling you, that your pinion angle is to far negative. If your measurments are "correct"""

Probably stupid questions compared to yours but I was wondering:
I am going to install the Hotchkis Leaf springs, does it change significantly the amount of pinion angle I should try to get?
What about snubbers setting for street cars, would you adjust them to become in contact at 1 degree? 0 degree?
Also, I've read somewhere that when you remove a driveshaft from the transmission you have to put it back at the same place in order to be in phase... I really don't understand this, is in it how the driveshaft is welded together that determine the phasing and not how you clock the yoke in the transmission?

If you go by the trans/diff way its 8*... which is too much EDIT most of the cast yokes have a tapper cast into the area you show the protractor....you would have a truer reading on the front surface where the bolts mount

Yes, From these numbers, your 8* down from tranny to pinion.

dammmm !!! another variable thrown into this ....... so now i need to pull the shaft and start over .... ? Mr. P - how much taper are we talking about ?? would you say 1 degree? 2 degrees ? we need a smiley figure that puts a gun in his mouth and blows his head off........
I dont really know... I never measured it but you
can see it.... just trying to warn you... you can
measure off the U-joint cap if you want... I made
up a quick little tool for measuring off the cap but
you can use a socket that fits and put your inclineometer
on the socket... you will notice that one side is
the pinion and the other is the drive shaft, just
take the reading at the bottom(closest to the ground)
