No problem! Here is am image of what you want to look for. Bare in mind that the pinion angle needs to be the same as dive line angle UNDER LOAD. So 5-7 degrees lower is what MP Performance books say per RustyRatRod.
Trust me, it ain't "per me", it's per Larry Shepard and company. ...and I wasn't trying to argue with the clutch theory, certainly that needs to be right......but in my mind, you want the pinion angle RIGHT before you start chasing demons, because if it's not, you'll keep chasin um.
