Which way should I go with pinion angle ??????????????????????

Forget about your perches.
You are confusing me.
Measure at the yolk like this.
You punkin should be pointing down. The oposite of the trans tail shaft.
Like a "z" sort of.
Picture them oposite. The wobble "cancels" each other out.
The variable is the punkin nose goes up under torque.
That's what the differnent settings, because of different uses.
A drag car is different than a street car cause it is always wanting to wind up.
A lot.

Chrysler had dual u joints in some Imperials to give the shaft a cv effect.
"Constant velocity".
Someone correct me if I've gotten anything wrong.
Like you wont! LOL
