Pinion Angle ?

[79driver]

Hey guys,
I'm getting a fullsize 9 inch cut down to EB width for my 69. Since he is welding on the spring perches he wanted to know where to weld them to get the desired pinion angle. He wanted to know what the stock pinion angle was and if i wanted any different for my lift. The problem is I;m out of town and dont have ay way of finding out? So...

!. what is the rear pinion angle on a stock EB?
2.What should i set the pinion angle to if I plan on running a 3.5 inch lift, or should i leave it stock and use shims as necesary.
Thanks

If it were me, I would have them left off until you can mock it up in the bronco.

The pinion should be 2 degrees below being pointed straight into the drive shaft.
