pinion angle.

[tylerrocks]

I am getting ready to build a 9" rear end for my car now that the motor is complete. I am having a housing shortened from an F-150, I will buy the centersection and axles new. What I need to know is if there is any good writeups (or advise) about measuring and setting pinion angle, as well as the specs. I would like to weld my spring perches as close as possible to the correct angle.

This link tells you how to measure but not the specs for welding the spring perches.
