I'm putting a steeda adj. UCA on today so I searched all the threads about setting the pinion angle. I'm confused, because there seems to be several different ways people are measuring to get the angle. I have a one piece d/s, so it looks like that makes a difference. Where exactly should I measure? Driveshaft at the rear and pinion flange?? Also, anyone have pics of what tool I should use to measure the angle? I'm gonna hit up home depot or sears today.
